This will</div><div>give us some idea of what threads are waiting for what.</div><div><br></div><div>It is hard to see how this could happen if the connection has been</div><div>closed by the server, though it is not clear if the ERROR REPORT you</div><div>give is dated/timed after the Java Client has hung for a bit, or happens</div><div>before and CAUSES the hang.
