A DESCRIPTION OF THE PROBLEM :
While running stress tests, one of the  java process crashes while handling alarms. The code in question creates lists, adds object ,converts lists to arrays and vice versa and executes queries against the DB (select, delete, insert)

We have been encountering java crashes on different JVMs in our system,
about 3-4 time a night, since we've upgraded to 1.5.0_17-b04. Each crash
is of type  SIGSEGV and occurs on one of the CompilerThreads.
The 'Current CompileTask' differs from JVM to JVM. 1. #
