> Key: HHH-2000

> Project: Hibernate3
> Issue Type: Bug
> Components: core
> Affects Versions: 3.1 beta 2

> Hibernate tries to bind a persistent object to a long variable in a SQL statement during a call to merge() on an object with a one-to-one relation.
> I originally posted about this problem here: http://forum.hibernate.org/viewtopic.php?t=948272&highlight=
> I have created and attached a junit test to reproduce the problem. When running against 3.0 or 3.1beta2 the ClassCastException is thrown all the way out, as shown in the forum post. The latest code from cvs catches the exception and logs it. org.hibernate.type.NullableType.java rev 1.10 is where the exception is caught. It seems like it should be logged and then re-thrown, but it's not. The debug log from the start of the merge() call to where it logs that it failed to bind the value is:
