Laird,
I would say this is a good use case. I would be curious to see
your mappedsuperclass hierarchy.
It looks like you found a case where the [m_superclassName] set
on the metadataClass of a child is null - line 107 of
MetadataAsmFactory.getMetadataClass returns null by design in this
case but is not handled. There are 10 places where may get a null
return including yours early in the predeploy.
I would raise a bug, attach some part of the model (I have an
Entity --> MappedSuperclass-parent --> ? so far) and we could
then look at this.
thank you
/Michael

Suddenly started seeing this stack trace in our Hudson builds. I
will check our mappings to see what's going on, but thought the
list might be interested in this. We make a fair amount of use
out of mapped superclasses, in case that helps.
Best,
Laird
