[Zope-dev] attempting to undo an un-undoable transaction gives "NotImplementedError" with ZODB 3.9.5

[Chris Withers]

Here's an example:

2010-08-26 22:49:01 ERROR txn.-1338986496 Failed to abort resource 
manager: <MultiObjectResourceAdapter for <ZODB.DB.TransactionalUndo 
object at 0x2d509f0> at 47516176>
Traceback (most recent call last):
   File "transaction-1.1.0-py2.6.egg/transaction/_transaction.py", line 
475, in abort
     rm.abort(self)
   File "transaction-1.1.0-py2.6.egg/transaction/_transaction.py", line 
548, in abort
     self.manager.abort(o, txn)
   File "ZODB3-3.9.5-py2.6-macosx-10.3-fat.egg/ZODB/DB.py", line 985, in 
abort
     raise NotImplementedError
NotImplementedError

This used to give a meaningful error message.

Anyone know why it no longer does?
