Subject [jira] Commented: (DERBY-815) Prevent unneeded object creation and excessive decoding in parseSQLDTA_work()
Date Mon, 20 Feb 2006 15:23:26 GMT
    [ http://issues.apache.org/jira/browse/DERBY-815?page=comments#action_12367043 ] 

A B commented on DERBY-815:
---------------------------

I applied the patch and ran my ODBC tests with no failures.  I haven't had time to do a full
review of the patch, but I did skim through and it looks like things are well commented now--so
thanks for doing that.

One note: the patch only updates the master files for jdk15; the "default" master file (master/prepStmt.out)
wasn't updated, so if you run the new test with any JVM earlier than 1.5, there will be a
diff.  If you have time to try that out and include that master update in this patch, that'd
be good.

Thanks for taking the time to follow-up on my questions/concerns.
