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

             Summary: memory store is broken in 5.11.0 for advisories (and probably other
issues as well)
                 Key: AMQ-5665
                 URL: https://issues.apache.org/jira/browse/AMQ-5665
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 5.11.0
            Reporter: Kevin Burton


We're running 5.10.2 and don't encounter this issue.  We're running a non-persistent broker
in production and testing so that's why we found this issue.

It looks like 5.11.0 introduced this issue.

Essentially Advisories fail to fire. 

It looks like it’s a bug with MemoryTransactionStore. Switching to persistent brokers fixes
the problem.

It’s because addMessage calls:

        } else {
            destination.addMessage(null, message);
        }

.. with an explicit null.

the message given is:

2015-03-16 12:54:17,538 WARN [ActiveMQ Transport: tcp:///127.0.0.1:56468@16161] org.apache.activemq.advisory.AdvisoryBroker
Failed to fire delivered advisory, reason: java.lang.NullPointerException

… and I saw this when I was running mvn test in the main ActiveMQ test suite (or at least
pretty sure I did) so this is happening not just in my code. 

The full exception , which I captured by setting a break point is below. 


java.lang.NullPointerException

... the core issue here looks like the message doesn't have a TransactionId and MemoryTransactionStore
has an addMessages which has a fall through of addMessage with a null context which then causes
the NPE.

Did messages have an implicit transaction Id before?
