Bugzilla Bug 94906

It seems like ibm-jre-bin and ibm-jdk-bin are no longer working
on ppc64.  I have an up-to-date ppc64 system, running kernel
2.6.12-rc5.  When I try running java I get:

$ java -version
JVMDG218: JVM is not fully initialized - will not do dump processing.
Segmentation fault

I think this was the only java available for ppc64. :(

Maybe someone could check with IBM on this and see if they have a
newer version?

Thanks.

Assigning to you guys since nobody from the java team has access to a ppc64
machine. Please advise.

happens with 2.6.11-r9 as well, please find the strace attached.

strace of running java -version

Coworkers on the JRE team have suggested that we're running an old version -
will try with sr1a

sr1a fails too - will see if it fails when sr2 releases

This problem is very odd. :-/

*** Bug 98946 has been marked as a duplicate of this bug. ***

I tried the new IBM sr2 version, but it had the same problem. The problem seems
to have someting to do with jit compiler, there is no problem to run java
programs when jit is disabled in my system(2.6.12-r4).

Any progress in this regard?

Sadly it seems the JIT compiler team isn't responding anymore.

For now, the workaround seems to be to disable the JIT.

This can be done with set/export JAVA_COMPILER=NONE or adding
-Djava.compiler=NONE to your java command.

IBM Java5 betas are out:

http://www-128.ibm.com/developerworks/java/jdk/java5beta/

I think it is a good idea to test them, isn't it?

Yes, I just tried IBM java5 beta, and it worked with jit enabled. I also ran
some apps 
including eclipse 3.1.1, jboss 4.0.2, and azureus, all of them worked well. i
noticed that 
this beta java5 was much faster than v1.4.2 under my system. 

ibm-jdk-bin-1.5.0 is in portage now. it is still hard masked but ~ppc64, so I
guess I can close this bug. That version will go stable as normal (4 weeks out
of p.masked and no bugs during this period). If anybody wants this still being
open, then please reopen.
