Thanks, I'll have a look at that
I'm probably going to hold out for the native port though.
Based on the fact that the native port when released as binary will be
certified ... where as the Linux one is already certified, yet there
isn't any way to guarantee that FreeBSD Linux compatibility is
certifiably as good
as native Linux (at least I don't know of such a test)

Hmm, looks like the Sun .java_wrapper currently enforces that for Linux:
if [ "${vmtype}" = "classic" ]; then
ttype=green_threads
LD_BIND_NOW=yes
export LD_BIND_NOW
_JVM_THREADS_TYPE=green_threads
export _JVM_THREADS_TYPE
fi

You could try removing the green_threads setting and see how it goes.
I was assuming because FreeBSD doesn't force a threading subsystem that
Linux wouldn't, but it looks like I was wrong.
BTW, mandating a specific threading subsystem goes against a core tenet
of Java. For instance, the JCK testing suite specifically disallows
tests
that rely on a specific underelying threading model.
