Description Fang Wenqi 2005-12-01 22:29:56 UTC

Distribution:
  SLES9 SP4 plus kernel 2.6.15-rc4

Hardware Environment:
  IBM OpenPower 720

Software Environment:
  IBMJava2-1.4.2 is installed automatically by SLES9.	  
  
Problem Description:
  Issue java -version, then it reports:
  JVMDG218: JVM is not fully initialized - will not do dump processing.
  Segmentation fault

Steps to reproduce:
  ~#java -version
  JVMDG218: JVM is not fully initialized - will not do dump processing.
  Segmentation fault

Additional information:
  1. I cannot run any java problem at this time.
  ~#java hello         
  JVMDG218: JVM is not fully initialized - will not do dump processing.
  Segmentation fault

  2. Disable JIT is a work around for this problem.
  ~#export JAVA_COMPILER=none 
  ~#java -version
  Warning: JIT compiler "none" not found. Will use interpreter.
  java version "1.4.2"
  Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2)
  Classic VM (build 1.4.2, J2RE 1.4.2 IBM build cxp641420ifx-20040722

  ~#java hello

  Hello World

Please attach the configuration file you used to build the kernel with.

When was the last time the test worked properly?

Comment 2 Fang Wenqi 2005-12-01 23:32:32 UTC

Created attachment 6746 [details]
kernel configuration file

I just testing kernel 2.6.15-rc2/rc3/rc4 on SLES9 SP4 this week, java failed on
all of them. I'm trying 2.6.14 now, will get the latest workable kernel and
post result here.

Comment 3 Fang Wenqi 2005-12-02 05:50:57 UTC

Correct myself, I'm testing on SLES9 SP3-rc, not SP4.

Comment 4 Fang Wenqi 2005-12-02 07:00:09 UTC

Tested linux-2.6.12, it met the same problem as 2.6.15. 
System encountered scsi error when booting with linux-2.6.9.

java works well with SLES default kernel 2.6.5-7.241-pseries64. I'll pick up
another machine to try linux-2.6.5 next Monday.

Comment 5 Ding Rui 2005-12-04 18:04:37 UTC

This problem reproduced on 2.6.15-rc4 (SLES9 SP4)

Comment 6 Ding Rui 2005-12-04 18:09:08 UTC

Oh,correct it.
This problem reproduced on 2.6.15-rc4 (SLES9 SP3)
not SLES9 SP4.

In reply to comment #1:
>When was the last time the test worked properly?

After testing, IBM java works on linux-2.6.11, however, fails on linux-2.6.12.
Hope this information is helpful for tracking the problem.

Comment 8 Anton Blanchard 2006-01-08 17:48:57 UTC

Can you test with after running:

ulimit -s unlimited

I think the address space changes went in around that time, and ulimit -s
unlimited will force the old layout.

Comment 9 James He 2006-01-10 22:52:58 UTC

Anton,

I tested it as you said on the stable kernel 2.6.15. The problem reproduced on 
this kernel.

Comment 10 Mike Ranweiler 2006-05-10 17:35:22 UTC

This is a java problem, fixed in the next release (of java).  It evidently
started after the noexec feature was added.  Can probably be closed, now.
