Bugid:	1
Type:	usage
Status:	closed
Release:	1.0
Synopsis:	Out of memory
Keywords:	memory OutOfMemoryError NoClassDefFoundError
Opened:	19980819
Fixed:
Description: The JVM Client98 program comes up OK, but then when I try to run benchmarks it fails with the error java.lang.OutOfMemoryError Appletviewer fails with a java.lang.NoClassDefFoundError complaining that it cannot find some file. What is the problem?
WorkAround: The benchmarks require at least 20MB of heap memory. On different systems they may require more heap, and will usually run faster with more heap. Many java interpreters have a property or command line flag to control the heap size. E.g. appletviewer -J-mx32m http://server/jvm98/SpecApplet.html

Release:	1.0
Synopsis:	Applet won't run. Security exception.
Keywords:	applet security file
Opened:	19980819
Fixed:
Description: I'm running Netscape Communicator, loading SpecApplet.html from the directory where I installed the suite, and all I see is a grey box. The applet doesn't run. I opened Netscape's Java console and saw the error message: Security Exception: class from local disk trying to access url:file:/home/jvm98/props/user
WorkAround: You're trying to run the applet from a local disk (file:/) and Netscape's security manager refuses to allow the applet to read files from your disk. First you should note that the run rules require for reportable results that you run from a web server instead of from a local disk. If you do this, then Netscape's security manager will not prevent the applet from reading the necessary configuration files from the applet host. However, you may want to run from the local disk for test purposes, not for public reporting of results. In this case you may use another web browser that allows you finer control of your security preferences, e.g. appletviewer from the Java Development Kit, Microsoft Internet Explorer, or HotJava. In this case you may need to set properties or answer dialog boxes giving authorization for the applet to read from your disk. See Advanced Topics for more information.

Synopsis:	Netscape 4.04 won't run

Opened:	19980819
Fixed:
Description: I'm getting errors with Netscape Communicator. E.g., all I see is a grey box where the applet should be, or I get an "Applet exception", or a benchmark "hangs" and never completes.
WorkAround: You need Netscape Communicator 4.05 or later. Also note that the JVM's in Communicator 4.05 for different platforms may be different. Open the Java Console and read the version of Java. Communicator versions based on 1.1.2 instead of 1.1.5 may have incomplete JVM implementations. Communicator versions 4.02 and 4.04 with JVM's based on 1.1.2 will run most of the benchmarks but _227_mtrt, the multi-threaded ray tracer, may not complete.

Fixed:
Description: I'm running the benchmarks from a web server, but my network monitor shows there is little or no HTTP activity going on. How can this be?
WorkAround: Were you running in application mode earlier? If so, you may have set your CLASSPATH to load from local disk when possible instead of from the web server. Check and reset your CLASSPATH, or log out and log back in.

Release:	1.0
Synopsis:	Corrupted installation
Keywords:	install IDE compile
Opened:	19980819
Fixed:
Description: Earlier I was running the benchmarks and everything was OK, but now some of them are consistently running faster or slower than before, and some of them are getting incorrect results errors. I'm certain that nothing has changed in my configuration. What could have gone wrong?
WorkAround: Have you been studying the benchmarks using an Integrated Development Environment? Such a tool is very useful in navigating the source code and examining relationships among classes. However if you're not careful it may recompile the source code which could make a benchmark run faster or slower. The run rules prohibit modifying the class files. Also, if there is a bug in the IDE's compiler, it could produce incorrect code causing the JVM class loader to reject the invalid class file, or producing incorrect results. The _999_checkit program can be used to detect recompiled class files or installations that have been otherwise corrupted. If that is the case you should remove the benchmark suite and reinstall.

Fixed:
Description: I'm running on a mainframe computer that uses the EBCDIC character set, and the benchmarks fail. There are dependencies on the ASCII character set. Unicode should be used throughout.
WorkAround:
Comments: Unfortunately there are areas in the benchmarks where the portability features available in the Java platform have not been used as they should be. These limitations may be addressed in a future revision to the suite that would also remove deprecated API 1.0.2 methods. Note: Bug 8 was split into two separate bugs, 8 and 26.

Opened:	19980819
Fixed:
Description: The results page shows up fine in my web browser, Netscape Communicator 4.04, but when I print it the bar charts disappear.
WorkAround: You need a web browser that can print applets, e.g. Netscape Communicator 4.05, Microsoft Internet Explorer 4.01, or Sun HotJava 1.02. If you're using an older browser, turn off Java and the SPEC ratio bar chart will appear as GIF graphs. It's not quite as nice as the Java applet graph, and the memory utilization chart does not appear, but you can view and print it in almost any browser.

When I first generated results pages they looked OK. But then I moved them to another directory and the bars charts are just gray rectangles.
WorkAround: Wherever you move results pages you need to also have copies of the GIF images and Java class files used by the pages. Normally (if you have not overridden the default location when you generated the reporting page) the required files are: * class/BasePeakGraph.class * class/Graph.class * images/spec-sm.gif * images/basebar.gif * images/invalid.gif * images/peakbar.gif

Description:	Provide means to run each benchmark in its own thread.
WorkAround:
Comments: Here are the changes I hacked in to my version of v20c/spec/benchmarks/ProgramRunner.java to get each autorun run to run in its own thread. This is useful if you have tools that let you profile individual threads (which we do). Here I've just hacked it in unconditionally. Obviously "the right thing" would be to have a command line flag (reuse -t?) that turns it on and off. I also don't really deal with the exceptions from t.start() or t.join(). On the other hand, I can watch HotSpot spending less time compiling for subsequent runs, and more time running compiled code. $ diff v20/spec/harness/ProgramRunner.java v20c-thread/spec/harness/ProgramRunner.java 391,392c391,393 < spec.io.FileOutputStream.clearCount(); < ((SpecBenchmark)prog).harnessMain( args ); --- > spec.io.FileOutputStream.clearCount(); > //((SpecBenchmark)prog).harnessMain( args ); > runInThread(prog, args); 499a501,526 > > void runInThread(Object prog, String[] args) { > Thread t = new java.lang.Thread(new ThreadRunner(prog, args)); > try { > t.start(); > t.join(); > } catch (IllegalThreadStateException itse) { > Context.out.println("runInThread: IllegalThreadStateException"); > } catch (InterruptedException ie) { > Context.out.println("runInThread: InterruptedException"); > } > } > } > > class ThreadRunner implements java.lang.Runnable { > ThreadRunner(Object p, String[] a) { > prog = p; > args = a; > } > > public void run() { > ((SpecBenchmark)prog).harnessMain( args ); > } > > private Object prog = null; > private String[] args = null;

Opened:	19980604
Fixed:	1.03_01, 1.03
Description: Observed on Win32/x86 and Solaris/SPARC. Observed on JDK1.1.6 and JDK1.2beta4. Using "filename = this.getPath()" in spec.io.File constructors broke _213 on JDK1.1.6 Win32. And I tracked that problem down to spec.benchmarks._213_javac.Main where the argument to -classpath is "lib/" which is the root cause of the problems we were seeing. "/" will not work on Win32 as file separator and using "/" is not 100% pure Java. _213_javac was failing with the following > errors on 1.2beta4-H - > > Javac benchmark starting... > JavaLex.java:43: Class java.io.InputStream not found in import.
WorkAround:
Comments: A solution would be to use just "lib" or "lib" + java.io.File.separatorChar. Using "lib", along with the File constructor fix, works fine on Win32 and Solaris, 1.1.6 and 1.2beta4. > Instead filename = this.getPath() should be used so that no assumption > is made about how file names are constructed. > > Also Mark Reinhold pointed out that it is not 100% pure to construct > filenames by concatenating Strings.

Status:	open
Release:	1.0
Synopsis:	Running SpecApplication doesn't work in JDK1.2
Keywords:	File.separatorChar JDK1.2
Opened:	19980824
Fixed:
Description: The bug is in spec/harness/SpecProps.java. The constructor should set userFile to (new File(baseDir, "props" + File.separatorChar + "user")).getPath(), instead of userFile = baseDir + "props/user". This applies to all the properties files. An even better fix is to set userFile to new File(baseDir, new File("props", "user")) thereby avoiding the explicit use of File.separatorChar. Using the File constructors instead of concatenating strings is generally the best way to write truly platform-independent filename-manipulation code. I think the "100% Pure" guide contains similar advice.
WorkAround:	Run as applet from web server
Comments: Running SpecJava as SpecApplication doesn't work in JDK1.2fcs builds as it is unable to the "props/user" file and hangs after throwing a FileNotFoundException. This is because it is trying to load /home/dviswana/specjavaprops/user instead of /home/dviswana/specjava/props/user. This bug shows up because File.getAbsolutePath does not return a trailing slash in JDK1.2fcs.

Description: Microsoft jview and SDK looks for .props and .spec instead of props and spec Run as an application you get the error java.lang.NullPointerException The error message in Java console: Error loading property file file: /C:/InetPub/wwwroot/specjvm98/.props/user: com.ms.security Run as an applet you get the error jview /a http://server/specjvm98/SpecApplet.html The benchmark came up with exception: java.lang.NullPointerException The error message in Java console: Error loading property file http://server/specjvm98/.props/user: java.io.FileNotFound Run from Internet Explorer there is no problem. Reported on NT Server 4.0 + Service pack 3, IE 4.0, IIS 4.0, and jview.exe version 4.79.2252. Also MS Java SDK 3.0 and MS Java SDK3.1. -- JDK-1.2fcs-L doesn't run the SPEC GUI. It seems to be more of the same with directory separator problems. On my WindowsNT box, with $ULJ pointed at /usr/local/java, and jvm98-1.03.01 being a SPEC JVM98 Client installation, patched with the 1.03.01 updater, I do: $ cd jvm98-1.03.01/ $ $ULJ/jdk1.2/win32/bin/java -version java version "1.2fcs" Classic VM (build JDK-1.2fcs-L, native threads) $ $ULJ/jdk1.2/win32/bin/java SpecApplication Exception occurred during event dispatching: java.lang.NullPointerException ... Error loading property file file:///E:/SPEC/jvm98-1.03.01props/user : java.io.FileNotFoundException: E:\SPEC\jvm98-1.03.01props\user (The system cannot find the path specified)
WorkAround: Use Internet Explorer to access the Microsoft JVM. Or rename or copy all directories: .class, .doc, .props, .images, .spec, .SpecDoc, and .License.
Comments: Maybe the JVM is interpreting ".\props" as ".props" because "\p" isn't a standard backslash-escape sequence. But since the problem occurs on both Microsoft and Sun JVM's it doesn't seem likely to be JVM bugs. This appears related to the directory separator bug 17, and it is known there are portability problems in the JVM98 code in how it treats directory separators.

Fixed:
Description: Microsoft Internet Explorer almost stops before the test finishes and I can't get any satisfactory results. With Microsoft's SDK-Java.31, the harness hangs during some benchmark run when a web server on the local machine is used. It doesn't happen with web servers on other machines. We tried both Microsoft's web server and the Java web server.
WorkAround:
Comments: From: pbk Tue Oct 13 18:11:25 1998 %Bin\SDK-Java.31\bin\jview /a http://localhost/jvm98/SpecApplet.html ? I find that it hangs at the beginning (!) of many of the tests. If I open the Java Console (not the SPEC console), sometimes typing at that will kick it into proceeding. If I open the SPEC console, I usually see it something like ======= _202_jess Starting ======= Run 0 start. Total memory=3735552 free memory=2475800 So it's into the next test. Is that the point at which it tries to load the classes for that test? Sometimes it just takes a while to get started, sometimes I have to tickle it (e.g. with a "t" on the Java Console), sometimes nothing works. Sometimes it hangs between the runs of the autorun, which shouldn't be loading classes (but it might be trying to open files). If I leave the SPEC console open it seems to do better for a while. Could it be stream flushing to a closed/unopened console stream? Of course, performance numbers with the SPEC console open will not be optimal. I don't think it's the "localhost" in the URL. On my PCs I'm running JavaWebServer (1.1.1). I've also pointed it at my Sun where I'm running a venerable version of Apache. It's more reliable that way, but not perfect. It has been reported that there is a Windows registry setting for TCP/IP parameters on the client that avoids this problem, but we do not yet know what that setting is and cannot confirm the fix.

Keywords:	Windows-98 JDK1.2
Opened:	19981002
Fixed:
Description: I tested JDK1.2 beta4 with Windows 98 about ten times on my two machines, but got satisfactory results only once on each machine. In many case, "***NOT VALID***" messages appeared with _213_ javac test. Besides I couldn't send reports with the following error: >Message Send error: java.security.AccessControlException: access denied (java.net.SocketPermission mail.yk.rim.or.jp resolve)
WorkAround:
Comments: Not enough information to diagnose or reproduce the problem. This looks like the security manager refusing to allow the program to open a socket to talk to the SMTP server, possibly because it could not resolve the host name. You might be able to change your security preferences to allow it. I'm not sure how 1.2 works. Previously I have run appletviewer so I can change its security settings through the menu. Another thing you might try is to enter the numeric IP address of the SMTP server, or of it and the web server, instead of using the alphabetic name. (E.g., 123.45.67.89).

Fixed:
Description: I get a pop up that says: InstallShield Java Edition One Java Virtual Machine found. Click OK to install the application. C:\WINDOWS\jview.exe If I click OK, the pop up goes away and nothing happens. Observed on NT
WorkAround: Since it sometimes works and sometimes fails on different machines, it's possible that re-installing your JVM or re-installing NT would fix the problem.
Comments: Attempts to reproduce the problem were inconclusive. This appears to be a generic problem with the operation of InstallShield on NT rather than a bug in the benchmark suite: Tried to run on a NT machine. Javainstallshield package hangs with JDK 1.1.6. The installation failed. We tried a second machine in the Lab and this time it ran with two different versions of JVM (1.1.6 and MS).

Synopsis:	Will SPECjvm98 support PersonalJava?
Keywords:	PersonalJava embedded memory
Opened:	19980827
Fixed:
Description: | 1. Will SPECjvm98 support PersonalJava (and maybe even embedded Java) ? No. The benchmark driver uses multiple frames and as I understand it, PersonalJava supports only a single frame. You may be able to work around this for test purposes by running the benchmarks from the "command line" as an application instead of from a web server as an applet. | 2. Is it suitable for small memory devices (<8MB) ? Probably not. Two of the benchmarks, _202_jess and _228_jack, run with as little as 2MB of JVM heap. So they might run in 8MB total memory. You could test this by downloading the original programs from their web sites: http://herzberg.ca.sandia.gov/jess/ http://www.suntest.com/JavaCC/ The other benchmarks require more than 8MB of heap. Beyond what you can freely download from the above sites, SPECjvm98 would only give you workloads and some components you may be able to adapt to your use. But then it's not particularly expensive either.

Synopsis:	Cannot use MacOS web server. File name length limitation.
Keywords:	filename MacOS
Opened:	19980927
Fixed:
Description: On the MacOS file names are limited to 31 characters. The test "_213_javac" requires loading classes which are longer than 31 characters (e.g. ArrayIndexOutOfBoundsException.class, CloneNotSupportedException.class, IllegalMonitorStateException.class, IllegalThreadStateException.class, IncompatibleClassChangeError.class, NegativeArraySizeException.class, StringIndexOutOfBoundsException.class). We usually solve this problem by one of three methods: (1) packaging the classes in a JAR or ZIP file, (2) creating a "mapping" file which maps shorter (unique) names onto longer names, (3) accepting (hopefully unique) truncated file names. Unfortunately (1) violates the "Test Environment" assertions, (2) requires building the mapping into the VM, and (3) requires a standard "truncation" scheme (a la Win3.1).
WorkAround: The easiest way around this problem for testing MacOS clients would be to use a web server on some non-MacOS system that handles long file names. However see also bug #26.

In some places a particular line termination character (e.g. '\n' for UNIX) is hard coded. Some systems handle multiple line termination sequences, but this will cause spurious errors on other systems. Character.LINE_SEPARATOR should be used instead.
WorkAround:
Comments: Unfortunately there are areas in the benchmarks where the portability features available in the Java platform have not been used as they should be. These limitations may be addressed in a future revision to the suite that would also remove deprecated API 1.0.2 methods. Note: Bug 8 was split into two separate bugs, 8 and 26.

Bugid:	27
Type:	rfe
Status:	closed
Release:	1.0
Synopsis:	Text files have UNIX line termination
Keywords:	LINE_SEPARATOR install Windows MacOS
Opened:	19980818
Fixed:	1.03_05, 1.03
Description: Documentation text files (*.txt) have UNIX line terminators (\n) instead of DOS line terminators (\r\n). The default program association for Windows is textedit which does not understand and translate different line endings appropriately.
WorkAround: For MacOS use BBedit, or a similar editor which automatically translates line endings from different systems.
Comments: InstallShield can be set to perform line ending translation at time of installation based on file extension. We had not used this feature in the 1.0 release due to a risk of translating a file used by the benchmark which could cause the test to fail validation spuriously. However, the only txt files in the benchmarks are in _228_jack and are not used for validation, so InstallShield translation is safe and should be performed.

Type:	bug
Status:	open
Release:	1.03_05
Synopsis:	Console button incorrect if window closed manually
Keywords:	console
Opened:	19981208
Fixed:
Description: Bug in gui logic -> manually closing console window throws off main app's view button ( console off/on ) state logic. I.e., if you close the console window using the window's own (platform dependent) close mechanism, the main window does not "notice" that it was closed. The label on the button incorrectly remains "Console Off" instead of "Console On".
WorkAround: 1. Always close the console window using the button on the main window, or 2. If you close the console window manually and the button label becomes incorrect, press that button once and it will become correct.

Synopsis:	Memory allocations listed are misleading
Keywords:	memory allocation
Opened:	19991215
Fixed:
Description: D:\jvm98>java -mx32m spec.benchmarks._201_compress.Main The benchmark program description said that this program allocates 334 MB of memory. But my jdk indicates that only about 119MB memory is allocated. I tried the other programs and found out that only 1/3 to 1/2 the total memory allocation indicated in the benchmark program description "Gc" field is reported by my JDK. I don't know which one is correct. Or maybe the total memory allocated indicated in the "Gc" field of program description is the total memory allocated in 2 to 3 iterations of the same program.
WorkAround:
Comments: Yes, the memory requirements listed are for a typical run of 3 iterations. For a thorough treatment of SPECjvm98 memory allocation, see A Study of the Allocation Behavior of the SPECjvm98 Java Benchmarks by Dieckmann and Hölzle, University of California Santa Barbara (TRCS98-33) http://www.cs.ucsb.edu/TRs/

Description: The doc comment says that the percentTimes100 field is: /** * The percentage run of the benchmark. The benchmark can be run at 1%, * 10% and 100% of its full length. percentTimes100 is used to represent * this value. */ However, the comment in props/user is correct: # Select tolerance for auto-run specified in percent times 100 # I.e., 200 means 2.0%. If successive runs do not improve by at least # this amount, then terminate an autorun sequence

Description: When I used the reporting page generating program as "java spec.reporter.Reporter -a -r myresult -o myresult.txt", the following exception occurred: >Exception in thread "main" java.lang.NoClassDefFoundError: > spec/reporter/AsciiReport > at spec.reporter.Reporter.main(Reporter.java:56) I found that spec/reporter/AsciiReport.class didn't exist and managed to fix the problem by generating the class file with javac. Then other class files of TextBlock.class and TextColumn.class were generated. Perhaps the installation program didn't installed the class files.
WorkAround:	Compile AsciiReport.java
