Mike Matrigali commented on DERBY-5121:
---------------------------------------

Are you still planning on first backporting the fix made to 10.7 into the trunk 
line?  Have you done any more work to determine if the out of memory is this 
change or something in your environment?    Given the issues we have had with 
triggers it may make more sense to go with the safe change for 10.8 and then 
later after 10.8 is cut you can check in your new fix to trunk and get testing 
there before putting it into a released codeline.

My interpretation of reviewing the change is that it should be safe and not 
cause unexpected out of memory.  It is basically just
making all code go through the existing code path that all pre 10.7 databases 
are already executing.

If you are uncomfortable with your current testing maybe you could post the 
exact patch against trunk that you are trying and someone else can run tests 
based on it.
