Core JAVA

[Riccardo BIgoni]

Hi,
I have a core dump (300MB) from JVM 1.3.1.09, and in my log it appears this msg:
# Java version:
# Java HotSpot(TM) Server VM (interpreted mode)
#
# HotSpot Virtual Machine Error, Internal Error
# Please report this error to HP customer support.
#
# Fatal: Illegal class file encountered. Try running with -Xverify:all
#
# Error happened during: scavenge
#
# Error ID: /CLO/Components/JAVA_HOTSPOT/Src/build/hp-ux/../../src/share/vm/oops/generateOopMap.cpp, 2114
#
# Problematic Thread: prio=7 tid=0x000bc298 nid=3 lwp_id=6474 runnable
#
Not found hs_err.log. Why ? Anyone has any suggestions ?
Thank.

Are you using JNI? Seems like you are using RogueWave to me.
Or some third party application..

Can you run the same java command adding the -Xverify:all switch to isolate which class seems to be the one thats causing this??

Try it on a different machine to see if the same error happens in which case the problem area will be the patches applied/preferences

Just another thought.
Try running it on a the latest JVM which is 1.4.01

I do not use the JNI, but Bea WebLogic. I have already tried with Xverify:all, but it is not changed nothing. On this system run 30 java-applications without problems. The patch they are installed to 23 set (last depot), but I cannot install 1.3.1.10 (or 1.4) why I have webLOgic 6.1....
This problem is random 1/3 core one day, one month without crash...
In other sistem (with same kernel, same patch), i not have a problem.
Thank.

All right : Seems like some stack and thread issues with java are involved.Make sure that you have all the patches mentioned at
http://www.hp.com/go/java

Then also try running with the parameter of
-XX:CompilerThreadStackSize=3072 and see if this *might* work

As I said upgrading seems to be your best bet
