I monitor -java, but I admit that with all the email I get,
I only read messages with "thread", "libkse", or something
like that in the subject line.  You see why I picked up
on this message :-)

I have jdk1.4.2p4 working on one of my boxes (all running
libkse) and it seems to be doing fine.  I don't have jboss
or many of the other java ports installed.  The jdk seems
to work fine for our home-grown applications.

There were some bugs fixed WRT SCHED_ULE.  If you are not
running up-to-date current or not in a position to do
regular updates, you may want to stick with SCHED_4BSD.

There is a freebsd-threads mailing list.  If you have problems
with one of the threads libraries, you may want to post there
especially if you have any relevent debug info.
