---------------------------------
Summary: [Java Broker] [AMQP 1.0] Broker can deadlock if a
consumer is closed while it is sending messages
Key: QPID-5571
URL: https://issues.apache.org/jira/browse/QPID-5571
Project: Qpid
Issue Type: Bug
Components: Java Broker
Affects Versions: 0.26
Reporter: Rob Godfrey
Fix For: 0.27
The I/O thread first takes the endpoint lock and then gets the consumer lock,
the queue runner thread takes the consumer lock and then tries to get the
endpoint lock.
By modifying the I/O thread to release the endpoint lock if it cannot get the
consumer lock we can avoid the deadlock.
