Bryan Pendleton updated DERBY-2487:
-----------------------------------
Attachment: startUpgradeTests.diff
Thanks Mike and Dag for the upgrade pointers. Those tests are awesome!
I was able to add tests for the new XPLAIN features, and, using those tests,
found and fixed a handful of upgrade issues, so I think upgrade now works.
Attached patch 'startUpgradeTests.diff' passes the complete regression
suite in my environment.
I'm still tracking down to-do's and fixme's, but would welcome
additional review of the patch by anyone who has time.
