Hello,

Any idea what would cause this exception (stack trace below)?  ActiveMQ
5.5.0 *embedded* broker, fwiw (I'm reluctantly using 5.5.0 despite this
error and the ConcurrentModificationException, since there's no 5.5.1
yet...hint hint).  Connection URL to two independent (non-networked) brokers
is:

failover:(tcp://mq01:61616,tcp://mq02:61616)?randomize=true

Curious what might be causing the interruption, and what this error
means...i.e. it doesn't look like any messages are being lost, but I can't
tell what the ramification (if any) is.

Thanks!  (and pretty please release 5.5.1 with the
ConcurrentModificationException fix!)
