Joseph Leong commented on OPENJPA-640:
--------------------------------------
Does this problem still exist for OpenJPA 1.2.2? If so, is it still innocuous
to OpenJPA functionality as noted by the description?
We're getting:
Exception in thread "Attachment 65390" java.lang.ClassNotFoundException:

> Previously, I had an old trick to patch the

> Remarks: the problem is merely about displaying a piece of stacktrace but
> there is no actual impact to the OpenJPA function. (that's why I marked the
> priority as minor.)
