Suresh's test case is in this message.

http://nagoya.apache.org/eyebrowse/ReadMsg?listName=derby-dev@db.apache.org&msgNo=232

Maybe the bug description and pointer to the test case should be added
to the comments in DERBY-1.

While I agree with the general concern about wording of FAQ messages, in
this specific case, given the simple test case from Suresh, isn't this a
clear case of a bug in Apple's JVM?

Joesph, I couldn't see anything in your posts that would indicate
otherwise, but I may have missed it as the discussion also included the
performance issue which is not strictly relevant here.

Dan.
