create table part1 (id int not null primary key);
create table part2 (part1 int not null references part1(id) primary key);
-----%<-----

The attached exception is thrown.

Stack trace
Comment 2 Andrei Badea 2007-01-08 17:23:11 UTC 
This is caused by the entity class model generating a part1 CMR field where
there already is a part1 CMP field. When the relationships are uniquified the
part1 CMR field is renamed to part2, but the CMR mapping is not touched. 

Simply renaming the CMR mapping as the respective CMR fields are renamed is not
possible, as seen in issue 83323.
Comment 3 Andrei Badea 2007-01-09 14:39:22 UTC 
Fixed.

Comment 6 crued 2007-01-15 20:39:17 UTC 
Is this related to issue 91743?

   http://www.netbeans.org/issues/show_bug.cgi?id=91743

I don't see the NullPointerException in the stack trace of the other issue that
is in the stack trace for this issue, but it seems like it could be related.
