Subject Re: [jira] Commented: (OPENJPA-235) SQL reordering to avoid non-nullable foreign key constraint violations

No.  I'm saying that if these secret tests rely on OpenJPA to detect  
foreign keys based on the above setting, then it's likely that the  
problem is in OpenJPA's ability to detect the existing foreign keys  
rather than in OpenJPA's constraint analyses and SQL ordering.  For  
example, I know in some versions of MySQL the standard  
DatabaseMetaData.getExportedKeys call didn't work unless the keys  
were created with ALTER TABLE statements rather than in the CREATE  
TABLE statement.
