------------------------------
Component/s: C++ Broker
> [AMQP 1.0 JMS client] Client hangs during connection.close()
> ------------------------------------------------------------
>
> Key: QPID-5439
> URL: https://issues.apache.org/jira/browse/QPID-5439
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker, Java Client
> Affects Versions: 0.27
> Environment: qpid-cpp 0.27 (latest trunk), amqp-1-0-client-jms 0.28-SNAPSHOT (latest trunk).
> Reporter: Ulrich Romahn
> Priority: Blocker
> Attachments: threaddump-1388121261214.tdump

> I am connecting to a cpp broker via the amqp-1-0-client-jms client and send 1000 simple text messages to a queue on the broker. After that, I am opening a second session to receive those 1000 messages.
> When trying to close the connection (calling connection.close()), the client "hangs". When I look at the broker (qpid-tool, list connection) I am still seeing this connection open.
> Debugging through the code, shows that there is a lock in the class org.apache.qpid.amqp_1_0.client.Sender at the following code in method close():
> ...
> _session.removeSender(this);
> _endpoint.setSource(null);
> _endpoint.detach();
> _closed = true;
> synchronized(_endpoint.getLock())
> {
> while(!_endpoint.isDetached())
> {
> try
> {
> _endpoint.getLock().wait();
> }
> catch (InterruptedException e)
> {
> throw new SenderClosingException(e);
> }
> }
> }
> It actually seems to hang at the line " _endpoint.getLock().wait(); "
> NOTE: the exact same code works when running against a Java broker 0.24.
