I have successfully test hsqldb-2.2.9 against the following 4 issues and 
it is functioning correctly:

and I have looked at

Unless I am looking at this wrong, many of the changes are not related to hsqldb19 and it
is already in the latest revision. As for the hsqldb specific, the patches does not apply
to 2.2.9. As far as patches, wouldn't it be better to report upstream and provide the patch
instead of just patching within the build? There are also checks within the code to specifically
check for version 1.8.x, not sure  wouldn't it be better to enforce on configure/bootstrap?
The current way seem to require a lot more work to update dependencies and the with-system-hsqldb
for configure provides no warning.

I will take a look at the open issues and see if it is resolved with the new version.

I am guessing my next steps would be looking into updating the build to pull the jar?
