-------------------------------------
[~yeongwei] Regarding the commit, you're welcome! We always give credit in the
commit message to the author of contributions. (It's the right thing to do.
And, it helps us keep our IP straight.)
Regarding hsqldb. I totally agree. I fought the same issues. Thanks for logging
the bug. (hsqldb is a great project and, to be fair, we are pushing their
boundaries with some pretty tricky SQL.)
