10.6 upgrade tests are disabled

[Rick Hillegas]

I would like to add some new cases to the 10.6 upgrade test. I notice 
that the 10.6 upgrade tests were commented out as part of submission 
768597 associated with DERBY-2487. When I uncomment the 10.6 upgrade 
tests and run them against the full set of releases on my machine, I see 
one instance of the following error:

1) 
testSetXplainStyleProcedure(org.apache.derbyTesting.functionTests.tests.upgradeTests.Changes10_6)java.sql.SQLException: 
'SYSCS_UTIL.SYSCS_SET_XPLAIN_SCHEMA' is not recognized as a function or 
procedure.

I am inclined to comment out this one case rather than the entire 
Changes10_6 test. Please let me know if there's something more deft 
which I should try.

Thanks,
-Rick
