-----------------------------------
Summary: [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: 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
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);
}
}
}
NOTE: the exact same code works when running against a Java broker 0.24.
