JDBCReader incorrectly generates bogus FK names
-----------------------------------------------

                 Key: HBX-1131
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-1131
             Project: Hibernate Tools
          Issue Type: Bug
    Affects Versions: 3.2.4.GA
         Environment: Tools 3.2.4 GA
            Reporter: Eric Sirianni


Please see my forum post@ https://forum.hibernate.org/viewtopic.php?f=6&t=996016&p=2416464#p2416464

JDBC drivers are allowed to return NULL for the "FK_NAME" metadata field for foreign keys.
In this case, hibernate tries to generate a bogus FK name.  This FK name must be unique for the Table otherwise an exception is thrown:
   org.hibernate.cfg.JDBCBinderException: Foreign key name (0) mapped to different tables!

Hibernate's algorithm for generating the bogus FK name appears to be wrong.  It should increment the bogus FK name for each FK it finds, irrelevant of the "KEY_SEQ" value.
