JDK 1.5.0: application crash with multiple threads

I have a multithreaded application that is crashing under JDK 1.5.0 when
using multiple threads. Works fine (and has worked fine for quite some
time) with JDK 1.4.2.
Brief overview of application:
- It's a batch-oriented RSS reader (i.e., no GUI)
- It can be configured to process RSS feeds in parallel, using up to N
threads. If N=1, it does not spawn threads, but processes the feeds
sequentially.
If I try to run it with more than one thread, in the alpha JDK 1.5.0, it
crashes with:
# An unexpected error has been detected by HotSpot Virtual Machine:
#
# SIGBUS (0xa) at pc=0x286f2377, pid=48305, tid=0x8625800
#
# Java VM: Java HotSpot(TM) Client VM (1.5.0-p1-bmc_03_apr_2005_13_15 mixed mode)
# Problematic frame:
# C [libverify.so+0x8377] VerifyClassForMajorVersion+0x5643
Other info:
1. This occurs with JDK 1.5.0-p1 on FreeBSD 4.11-RELEASE. The JDK was built
on the same machine.
2. The machine itself is a 2.4 GHz Pentium 4 with 512 Mb of RAM
3. The application runs fine under JDK 1.5.0 without threads.
4. The same application runs fine with multiple threads on a Linux machine,
using the Linux 1.5.0 JDK.
5. The same application runs fine with multiple threads on FreeBSD, using
the FreeBSD 1.4.2 JDK. In fact, I have been running it with the FreeBSD
1.4.2 JDK on FreeBSD 4.10/4.11 for a long time, without any problems.
(It also runs fine on FreeBSD 4.8-RELEASE, with the 1.4.2 JDK, with no
problems.)
6. It doesn't seem to matter whether the code is compiled with the 1.5.0
javac compiler or the 1.4.2 javac compiler.
7. Specifying the "-server" option to "java" makes no difference. (It
seemed worth a try...)
I've enclosed the output from the trace (i.e., the "hs_err_pid*.log" file)
that's produced when the VM dumps core, as well as a stack trace retrieved
from the core file via gdb(1).
I can reproduce this problem at will. I'd be happy to run additional tests,
try other things, etc.
Is there a known problem with threading in the 1.5.0 JDK?
Is there any other information that would be useful?
