NEW

If I force a brokenConnection.close() into the onException callback, (called
when the "other" connection is broken), my process can now terminate
gracefully and is not blocked waiting threads die.

However there is a JMSException thrown by this "close" on a
brokenConnection. But it is not a big problem.

I think it is not the way ActiveMQ should work.
