---------------------------------
Summary: synchronized store and getMessages of JmsPullPoint would
cause deadlock
Key: CXF-7145
URL: https://issues.apache.org/jira/browse/CXF-7145
Project: CXF
Issue Type: Bug
Components: Services
Reporter: Freeman Fang
The JmsPullPoint would be accessed by both the producer client and consumer
client, currently the whole store(used by producer) and getMessages(used by
consumer) method was synchronized. For some flow control scenario[1], the
{code}
producer.send(message);
{code}
in store method would be blocked if the jms queue exceed some certain size, in
this case the getMessages method never get chance to be invoked to decrease the
queue size which cause deadlock.
Actually in the methods only the session is critical resource which should be
synchronized, so we should synchronize the session only to avoid this deadlock
