Kevin Sutter commented on OPENJPA-370:
--------------------------------------
Due to the performance concern comments, I have backed out these changes in my
own sandbox and am running our performance suites trying to validate the
problem. If the results indicate such a significant performance degradation,
then I will gladly back out the changes until we figure out the proper solution.
One thing that I immediately noticed is that the testcase that we committed
with these changes no longer works.
http://svn.apache.org/viewcvs.cgi//openjpa/branches/1.0.x/openjpa-persistence-jdbc/src/test/java/org/apache/openjpa/persistence/fetchgroups/TestFetchGroup.java/?rev=580995&view=markup
So, maybe the first step is to validate the testcase. Could one of the
interested parties that knows more about the intent of LoadFetchGroups (better
than me) review this testcase?
Thanks,
Kevin
