Hi Tom
 I am attaching code changes relevant to Issue 267.
This is a case where the user has defined Inheritance strategy of
"JOINED" (or "SINGLE_TABLE") and not defined a DiscriminatorColumn or
DiscriminatorValue annotations.
In this case in the current code there is a bug where we would get a
NullPointerException for the DiscriminatorValue part.

I have attached the changed source and the cvs diff file.

Thanks
Pramod
