Classloader conflict when using IBM W-MQ OSGi bundles in Fuse 6.3.0

Issue

This problem is seen when using the OSGi version of the WebSphere MQ (W-MQ) client runtime with Fuse 6.3.0. A Camel route that communicates with W-MQ fails to start, and the following message is seen in the Fuse log:

Caused by: java.lang.Exception: Unable to convert value |   com.ibm.mq.jms.MQConnectionFactory@c79b6829  :-
