We recently upgraded to FUSE ESB Enterprise Version from old version apache-servicemix-4.4.1-fuse-01-13 to a new version fuse-esb-7.1.0.fuse-047 in our UAT that causing the issue guessing with the changes below:

Changes in the BodyType (I have find the following changes in the BodyType of the messages)

QA (new version): BodyType: org.apache.servicemix.jbi.jaxp.StaxSource

QA (old version): BodyType: org.apache.camel.converter.stream.SourceCache

The above changes causing the below exception while posting the request to our endpoint "To-VzServiceBridgeEndpoint"
