Would it be possible to get the source code of this class?
QA/src/com/g/test       Test.java

Do you reproduce it all the time? Does it work with a full build ?

No, it happened only once.

Comment 3 Olivier Thomann 2007-01-19 11:46:02 EST

Did you have compiler errors when this happened?
Without further information, it will be difficult to track it down.

There weren't any compiler errors at the time.
This happened to me only once. apologies for the lack of information. 

Comment 5 moran 2007-02-22 07:05:45 EST

Got it several more times, and there were no compile errors noticeable.
I will move to 3.3M5

Did you get it again since you moved to 3.3M5?

Would it be possible to get the code of the file mentionned in comment 1, please?
I might have a clue of what is going on, but I would need a test case to reproduce.

Comment 8 Olivier Thomann 2007-03-02 12:12:36 EST

Did you get compile errors beside this exception in your test case?

Comment 9 moran 2007-03-15 04:18:58 EDT

No compile errors were apparent. There is nothing special to this file, and the file occurrence changes. If I run into it again, I will attach the file mentioned.
Since I moved to 3.3M5 I did not encounter it, but it wasn't that frequent to begin with.

Comment 10 Adam Domanski 2007-04-12 05:04:49 EDT

I've also encountered the problem. It appears with my Eclipse (3.2.1 and 3.2.2):

eclipse.buildId=M20070212-1330
java.version=1.5.0_08
java.vendor=BEA Systems, Inc.
BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=pl_PL
Command-line arguments:  -os win32 -ws win32 -arch x86

It appears on different classes each time I build the project. Project is quite big, about 8000 Java sources.

Compiler settings for projects are: source level compability with 1.5, target 1.5, JRE 1.5 (JRockit). If I change source level compability with 1.3, then there is no such problem.

I can send You a class, on which compiler crashed, if You wish.

Comment 11 Philipe Mulet 2007-04-12 05:34:05 EDT

Feels like we would rather need your entire workspace. Is that feasible ?

Comment 12 Adam Domanski 2007-04-12 05:52:40 EDT

I am sorry, but I cannot share my whole source code with 3rd party libraries.
I will try to create smaller project and reproduce the problem if it is possible at all.

Comment 13 Adam Domanski 2007-04-13 04:15:16 EDT

I spotted that launching Eclipse with Sun JVM or with JRockit but with no bytecode optimization (using -XnoOpt switch) have not caused the problems yet.

Although I need some time to verify it in daily work with Eclipse.

Comment 14 Philipe Mulet 2007-04-13 07:06:25 EDT

Could also be a timing issue in our layer (which is hidden when JIT is off), though from the trace you gave, it feels unlikely.

Comment 15 Olivier Thomann 2007-04-19 13:05:52 EDT

I am still unable to reproduce this one. If you have any clue that can help, please let me know.

Comment 16 Adam Domanski 2007-04-20 02:21:23 EDT

I'be been working for a week with JVM Sun 1.5.0_11 and JRockit 27.2.0. As the problem didn't occur in these JVMs anymore, I suspect problems inside JRockit 27.1 code optimization.

Comment 17 Olivier Thomann 2007-04-21 16:56:37 EDT

Closing as WORKSFORME then since the initial comment also states the JRockit 27.1 VM.
Please reopen if you get it again.

(Discussed the motivation for this with Olivier, agree with him.)
