[jira] Created: (QPID-193) AMQSession.createConsumer must be
synchronous to avoid timing problems
AMQSession.createConsumer must be synchronous to avoid timing problems
----------------------------------------------------------------------
Key: QPID-193
URL: http://issues.apache.org/jira/browse/QPID-193
Project: Qpid
Issue Type: Bug
Components: Java Client
Affects Versions: M1
Reporter: Robert Greig
Assigned To: Robert Greig
Several people have noticed occasional failure in some tests.
In particular tests that create multiple connections can fail intermittently. This looks to be some kind of race condition.

[jira] Commented: (QPID-193) AMQSession.createConsumer must be
synchronous to avoid timing problems

Robert Greig commented on QPID-193:
-----------------------------------
Analysis shows that the problem occurs in tests that set up consumers on one connection and publish on another. At some stage createConsumer was made asynchronous so that when the Session.createConsumer call returns the consumer has not necessarily been set up. This means that if the test goes on to publish to a topic it may be the case that the consumer's private queue has not been bound to the exchange. I am not sure why this was made asynchronous in all cases.
The solution is to use the nowait flag to make createConsumer synchronous (only making it asynchronous when used for failover resubscription).
