AMQP 1.0 JMS client simply accepts the heartbeat frequency requirement that
is communicated to it by the server it connects to.  Since this works with
other servers, my suspicion would first be that HornetQ is not properly
communicating its requirements to the client (this should be sent in the
idle-timeout field of the open frame).

The AMQP 1.0 JMS Client uses java.util.Logging for log output.  If you
configure it such that the FRM Logger outputs fine level output then the
following lines in ConnectionEndpoint.java should print out the frames
received from the Server.

private final Logger _logger = Logger.getLogger("FRM");

    public synchronized void receive(final short channel, final Object
        if (_logger.isLoggable(Level.FINE))
            _logger.fine("RECV[" + _remoteAddress + "|" + channel + "] : "
+ frame);

If you look for instances of the Open fram being received then you should
be able to see what value (if any) the server is setting idleTimeout to.

Hope this helps,
