running the cdi tck. I think it means that the weaving code is converting a
NoClassDefFoundError due to a missing superclass into a ClassFormatError. This
seems like a mistake. A lot of code can deal with a NoClassDefFoundError and
its more or less expected sometimes but ClassFormatError is much less usual.
In particular OpenWebBeans tries to load every class to look for annotations
and doesn't worry if it cant load the class but it's not set up to deal with
ClassFormatErrors.
I'm thinking this might be a good idea:

and it seems to fix the immediate problem.
thoughts?
