Albert Lee commented on OPENJPA-525:
------------------------------------

Milosz,

Thanks for trying the patch on MySQL.

I did not run into any problem in Derby and DB2. Probably it is some db 
specific feature.

How is the failure surfaced in the test? What is the symptoms looks like? Do 
you have any exception stack to look at ? Do you have any idea what may have 
gone wrong? Not sure how is the patch affect Oracle db?

Albert Lee.
