Hi,

I'm running pms (playstation media server) inside a jail on one of my systems.
I used diablo-jre until now but wanting to migrate to openjdk as diablo-jre is
no longer available.
But - for unknown reasons - when I start "pms" with openjdk-jre, it does not
do any network communication.

When started with diablo-jre I can capture with tcpdump the following data:

bigoli is the jail gurke-re0 is the host system.

So far so good - when started with openjdk 6 (jre), it does not send  
anything over the network while the software itself claims to send  
ALIVE signals without any indication of an error. Is there something I  
could debug to find out what is going on with openjdk on FreeBSD?

PS: please keep me CCed.
