to http://localhost:8080/http-bean-service/

------ End Message Trace -------
In the method org.switchyard.interbnal.DefaultMessage.getContent(..), lines 104-108, it tries to find transformer for same fromType and toType, which throws NPE.
I'm not sure whether transformations should be processed in this code at all, if message was transformed before it enters bean execution.
Reproducible apps are attached to the bugzilla.
