Hello Simon,
I'm sorry I am not familiar with most of the components you mention in
your report.
But I did noticed that in the stacktrace you see this:
org.apache.servicemix.bundles.qpid:0.28.0.1
That made me think maybe servicemix is bundling version 0.28 of the Qpid
Java client libraries.
Usually "bad things" happen when mixing libraries from different versions.
Kind Regards,
Lorenz

I have an issue which I have described here

-issue
In summary:-
1) OpenNMS is using QPID 0.32 Java Client to talk into a 3.5.7 Rabbit
MQ Server from within an Apache Karaf bundle using a camel blueprint
2) Sending a message to an exchange with a bound queue on the backend.
3) It is failing with a null pointer exception
java.lang.NullPointerException

4) I can get this working from outside of Karaf using the same client
version (0.32) and address string which validates both the connection
parameters, the address string and the function of the rabbit mq server.
5) If I trace this out within qpid it seems to get a connection but not
transmit any data

Can you suggest what the issue might be?
