Hi Christopher,
I haven't verified this is the case, but it looks likely - the testcase for
OPENJPA-843 passes when I use the enhancer.

It may also be worth noting that we recently changed the default option for
RuntimeUnenhancedClasses from supported to unsupported in OPENJPA-651. The
change affects trunk and 1.3 (IIRC) and was done to try and prevent users
from falling into situations like this one where the unenhanced classes
don't work properly.
