 From my experience, that is what folks will assume, even if the FK  
constraints are not declared or automatically detected. And the only  
harm in reordering SQL statements is that sometimes OpenJPA would  
reorder statements that didn't need to be reordered, or in extreme  
cases split a SQL statement into two due to perceived but not real  
circular dependencies.
