NullPointerException in DataCache

[Roger Keays]

Does anybody recognize this exception? It seems to occur mostly on
transactions with updates and deletes. It hasn't occured on any persist
  operations.

If I turn off the DataCache the problem goes away.

Hi,
It was a bug.
It has been fixed with revision 633739.
Apparently related to handling instances of type that is not L2 cached.
