  it seems to be a problem with the Sun JVM.

 More than likely just a compatibility problem.  There's been a few things
 that have changed with the new JDK.  Also, the new JDK is supposedly more
 stable than the 1.3.x series.  1.3.x was unstable as all hell.

One shouldn't use Linux JDKs on FreeBSD to run anything
except trivial 'hello world' -type programs. There are problems
on FreeBSD linux emulation, which cause a Linux JDK with
hotspot enabled to go boom very very easily.

There are two options: Either use Linux jdk 1.3.1 with
classic VM (-classic option) or build native FreeBSD jdk 1.3.1
and use it. Both these solutions currently have poor performance
(unless you get some kind of JIT working with native
one - there are several alternatives). However, people
are working to get HotSpot enabled on native JDK - once
that happens the performance should be good. Until then,
if you need performance, go for Linux (as sad as it may sound).

There are known problems running linux-jdk on FreeBSD with hotspot
enabled. These problems tend to pop up with anything that uses threads
heavily, like Tomcat. I would expect JBoss to fall in this category also.

When running in classic mode (ie. java -classic ) things work
OK, but performance is not good. I am using both Linux jdk this
way and also native FreeBSD jdk (beta) to run Tomcat on small
systems without any major problems. I would expect
JBoss to work also OK, there shouldn't be threading problems
similar to those running on Linux, since classic mode uses
JVM's internal theads.
