NullPointerException thrown in ManyToOne.java
---------------------------------------------

                 Key: HHH-3208
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3208
             Project: Hibernate3
          Issue Type: Bug
          Components: core
    Affects Versions: 3.2.6
         Environment: Hibernate 3.2.6; Database: N/A
            Reporter: Karol Nowak


Hibernate dies with ExceptionInInitializerError due to a NullPointerException being thrown in ManyToOne.java (see the trace below) when a property-ref attribute is set to a nonexistent property group. That's annoying and difficult to debug. Instead, Hibernate should inform that there's no matching group.
