Summary: ConcurrentModificationException on server shutdown

Hello,

I sporadically get a
java.util.ConcurrentModificationException on the
client side when i shut down the openjms server. This is
annoying
because my ExceptionListener won't get called and this
in turn prevents
my failover to be triggered. I'm using openjms-0.7.6.1.

I had a look at org.exolab.core.mipc.Demultiplexer and
after adding a
bit of synchronisation it worked fine.
