[OJB-developers] Exceptions once again

[<Joa...@tp...>]

Hy,

I once again stumbled over a case where the root exception is lost. This 
time it's in the ODMB-Implementation and throwing a ODMB-Exception which 
make the case a bit more complicated.

My question is: Is it possible/legal to modify or subclass the 
ODMG-Exceptions while still beeing a compliant Implementation? (I don't 
have the ODMG-Standard (actually, I just found Version 1.2 of the Standard 
from 1993 some days ago for 2 Euro and bought it, but it doesn't have 
Java-Mappings in this Version ;-)).

If this is not possible, we could introduce an Exception-Helper that let 
us set the cause for non-OJB-Exceptions without changeing their code. This 
class would do almost the exact same thing as what my Patch for 
PersistenceBrokerException does.

I'd like to ask you what you think of such a class. Additionally I'd like 
to ask if this counts as a new "Feature" and therefore is forbidden, due 
to feature freeze.
