BEA has a test case they can send. It will need weblogic server to run.

1.3.1_04 using -XX:+ShowMessageBoxOnError and heap sizes of -Xms32m -Xmx200m
Crashes with both -server and -client compilers.
other stack traces are in /net/cores.east/cores/63117078

gets the following error and then attaching dbx to the process gets the following stack trace

An irrecoverable stack overflow has occurred.
Unexpected Signal: 11
An error has just occurred, do you want to debug the problem?


from my server log, then I run dbx from another shell like following:

$ /opt/SUNWspro/bin/dbx
/home/ytian/jdk/j2sdk1_3_1_04/bin/sparc/native_threads/java 6614
changes (topic)
The major new features of this release relative to 6.1 are:

o The dbx environment variable "rtc_use_traps" has been removed.
   Traps are used automatically as long as the hardware is UltraSparc.
o There is now some basic support for looking at core files from
   different versions of Solaris. See `help core mismatch' for details.
o Stepping to a specific function support. See `help step to' for details.
o Fortran intrinsics support on Intel has been removed.
o Dbx automatically translates some old dbxenv variables to their new
   names. See `help dbxenv' for details.
o The default command-line editing mode is now emacs. See "How do I enable
   command-line editing?" in FAQ for details (`help FAQ').
o Two new collector commands have been implemented: `pause' and `resume'.
   See `help collector' for details.
o The collector enable_once command has been removed.
o The collector store command has been extended to include experiment groups.
