Keith Wall created QPID-7253:
--------------------------------
Summary: [Java Client 0-10] Application allowed to created new JMS
session whilst failover is in progress
Key: QPID-7253
URL: https://issues.apache.org/jira/browse/QPID-7253
Project: Qpid
Issue Type: Bug
Components: Java Client
Affects Versions: qpid-java-6.0.2, qpid-java-6.0, 0.32, 0.30
Reporter: Keith Wall
Unlike the 0-8 path, creating a JMS session {{Connection#createSession()}} does
not take the failover mutex. This means that an application's call to
createSession does not block whilst failover is in flight. This gives rise to
a race between application's creation of the new session and the
re-subscription of the existing sessions. In an unlucky case, the client may
cause try and attach the same session twice. This will be rejected by the
Broker with a SESSION_BUSY.
