Long similar foreign key names are shortened to conflicting names
-----------------------------------------------------------------

         Key: DDLUTILS-106
         URL: http://issues.apache.org/jira/browse/DDLUTILS-106
     Project: DdlUtils
        Type: Bug

  Components: Core  
    Reporter: Christoffer Hammarström
 Assigned to: Thomas Dudziak 


In my generated sql for Oracle, i find the following two conflicting statements:

ALTER TABLE doc_permission_sets
    ADD CONSTRAINT doc_permission_ermission_sets FOREIGN KEY (set_id) 
REFERENCES permission_sets (set_id);

and 

ALTER TABLE doc_permission_sets_ex
    ADD CONSTRAINT doc_permission_ermission_sets FOREIGN KEY (set_id) 
REFERENCES permission_sets (set_id);

The tables have similar names, and the foreign key names conflict.

Oracle gives the following error when trying to run the sql:

 ORA-02264: name already used by an existing constraint

Maybe SqlBuilder.shortenName() could use some kind of counter for conflicting 
names?
