----------------------------------
Summary: Creation of consumer hangs when connection is in a
process of re-establishing by failover
Key: QPIDJMS-242
URL: https://issues.apache.org/jira/browse/QPIDJMS-242
Project: Qpid JMS
Issue Type: Bug
Components: qpid-jms-client
Affects Versions: 0.11.1, 0.20.0
Environment: Qpid Broker 7.0.0-SNAPSHOT
Reporter: Alex Rudyy
The creation of consumer (Session#createConsumer) hangs if invoked when
underlying connection is being re-established by failover process. Even when
failover successfully restores the connectivity, the invoked method
createConsumer does not return. I see the following in the stack trace:

The consumer is created successfully on broker side. Broker even sends the
messages through.
