to re-run the regression suites later today to make sure everything is still okay (esp. since
some DataSource tests were added to suites.All aftet I posted the patch), and if everything
passes then I will likely commit  d2488_v4.patch before the end of today (Friday).

I wonder, is your patch accidentally also solving
https://issues.apache.org/jira/browse/DERBY-2559?
I won't have time to check this until later...But just pointing out
that part of test DataSourceReferenceTest currently is not running
with JDBC4 jvms.
