Hibernate ORM / Bug HHH-8580
NPE while deleting items from collection
Hibernate throws a NPE while deleting objects from an entity with a query like this one:
{code}
DELETE FROM UserData d WHERE d.user = :user
{code}

The problem is present only from hibernate 4.2.2+, while versions up to version 4.2.1 it works fine.

The stack trace is:
{code}
Unexpected error: java.lang.NullPointerException
java.lang.NullPointer...
