I wonder if what's going on is that the test case is getting it's hands on the Entity classes before we're loaded and able to tell OpenJPA that the classes need to be dynamically enhanced. OpenJPA's unenhanced support is ok, but not feature complete.

One way to verify would be to split your test case into two classes; the TestCase subclass which would do nothing more than setup OpenEJB via the InitialContext and have a test method that delegated to your second class which actually did test. The idea being the second class which references the entity classes wouldn't get loaded until after the first class has run and setup the dynamic enhancer.

Let us know if that's the case as we can probably document this kind of OpenJPA specific testing technique. Definitely in Java 6 this kind of thing will be easier as class redefining is there as well as being able to install an enhancer post-startup (i.e. no agent).

I'm running into a mild annoyance running a junit test suite directly from within Eclipse. I have the -javaagent VM arg in my run configuration, and
the problem does goes away if I run an ant task to call the enhancer
directly prior to running my test suite.

The problem is that access to any collection from the first Entity listed as 'subclassed' gives an NPE, which in my configuration is a failure. The remaining Entities test fine, and you'll notice that the enhancer happily
processes that Entity after reporting it being subclassed.

As I stated, it's a mild annoyance because when any tests fail, I only have
to launch that ant enhancer task and re-run the test.  Any thoughts?

following is a portion of my test suite output:
