Issue using @Transactional and @Context in a CXF REST Endpoint with spring-data-neo4j

I'm mixing spring-data and CXF to create a RESTful endpoint that creates neo4j nodes. My structure is a set Interfaces which define the public facing methods, and my implementations which have several private methods under that are called by my public methods.

When I do create a public method, I get a proxy casting issue:

Code:

I have update my GitHub project below:

What is wrong with my code?
