A little known fact about JBoss

It seems that JBoss caches DNS name lookups.

This means that if you change the ip address of a remote service while leaving the hostname the same, JBoss won't realize this. When you try to debug why JBoss is failing, it will be very confusing because everything says that it should work but the hidden ip address embedded in the socket connection still points to the old service.

Bad JBoss.
