Subject [jira] [Commented] (DERBY-5010) [patch] bad equivalence check
Date Wed, 15 Jun 2011 04:17:47 GMT

Bryan Pendleton commented on DERBY-5010:
----------------------------------------

If it's definitely the 'aggregate' test which is touching the code, then you should be able
to confirm this by doing something like:

  java org.apache.derbyTesting.functionTests.harness.RunTest lang/aggregate.sql

with and without your "System.exit(1)", and see the test pass without your change, and
exit early with your change.
