> I've tried to use composite keys through the IdClass annotation, but the merge operation fails with the following error.  I used the ApplicationIdTool to generate the IdClass object.  What's odd is that I can take that exact same code and just switch the logic to use the Embeddable/EmbeddedId annotations and the merge command works.
