Description Rick Barkhouse CLA 2010-12-06 10:00:56 EST 
When generating a dynamic project, if I have a mixture of dynamic and static classes (e.g., a dynamic class which uses a static xml java type adapter), the dynamic framework treats the static class as if it was dynamic, looking reflectively for the DPM field.

In DynamicTypeBuilder, we should add a check to only look for the DPM field if the javaClass in question is indeed a dynamic one.
