Subject Re: Delete by query

Just a note on the completeness of the TCK. There are not many tests  
that are in place to test the behavior of deleting instances in this  
particular case (non-cascade, non-dependent, join table for one-many  
relationship).

We do plan on adding test cases in this general area for the JDO 2.1  
Maintenance Release.
