Re: connection.close(), on a brokenConnection resolves my problem

Unfortunately, all my problems are not resolved ... I tried with two equivalent processes on two different servers (and the third which is abruptly closed). One terminated gracefully, the other had always 2 active threads

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.
