java 1.5 crashes

[Sebastiaan van Erk]

Hi,

I'm having a lot of JVM crashes with java 1.5.

#  SIGSEGV (0xb) at pc=0x4851de79, pid=77384, tid=0x8421000
#
# Java VM: Java HotSpot(TM) Server VM (1.5.0-p4-root_28_apr_2007_09_58 
mixed mode)
# Problematic frame:
# V  [libjvm.so+0x38ee79]

They pretty much always seem to crash while doing the classloading:

Stack: [0xbe09f000,0xbe0df000),  sp=0xbe0dcdc4,  free space=247k
Native frames: (J=compiled Java code, j=interpreted, Vv=VM code,

I've seen the problem on multiple FreeBSD machines, releases 5.5, 6.2, 
etc. The JVM is the most recent ports version:

java version "1.5.0-p4"
Java(TM) 2 Runtime Environment, Standard Edition (build 
1.5.0-p4-root_28_apr_2007_09_58)
Java HotSpot(TM) Server VM (build 1.5.0-p4-root_28_apr_2007_09_58, mixed 
mode)

I'm planning to recompile the port with debugging information so that 
there are line numbers in the trace.
I have both the log and the core saved, so if I can help in any way, 
don't hesitate to ask!
