There might be two different issues here.
I made a mistake with the commit referred to below, and only ran the one
test case (the "test.basic.dynabean" target) for the classes I was
modifying, and not realizing that the tests for WrapDynaBean would inherit
the new testing. This caused a failure in the "test.wrap.dynabean"
target. I just checked in a patch for that.
If you do a fresh checkout and build and still have the problem, we might
indeed have a 1.3 versus 1.4 issue (I build everything with 1.4). Are you
still encountering this after picking up the change I just committed?
