I occasinally see this NPE on EJB module creation. I do not have a pattern in
which this happens

Vijay,
Unable to reproduce (even with the delete then create)  Either way the code
traces down to the builders which will be gone very soon .....please reopen if
you find a reproducable senerio though and i can take a look.
