----------------------------------

             Summary: JDBCPersistenceAdapter: queue messages trapped in store when DB connection
is lost and restored
                 Key: AMQ-4934
                 URL: https://issues.apache.org/jira/browse/AMQ-4934
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 5.9.0
            Reporter: Dejan Bosanac
            Assignee: Dejan Bosanac
             Fix For: 5.10.0


Periodically messages are being trapped in the store and not delivered to consumers when the
broker (using JDBC Persistence adapter) loses and then restores its connection to the DB.
The issued appears to occur when the connection to the DB is lost while the message is being
committed to the DB - the message is committed to the DB but the broker does not know it has
been committed as it receives an exception during the commit operation.
When the DB connection is restored the message will NOT be loaded from from the store. The
trapped message is NOT added to the Broker JMX statics - it is only seen by querying the DB.
The message will be loaded when the broker is restarted.
