In it's infinite wisdom, Libreoffice does not tell us exactly what went wrong. Upon further investigation (like 16 hours worth), it seems to be that hsql won't compile on JDK11 without a patch (adapts it to no longer use a certain method that was removed). There is also a build problem later on due to JDK's changes to Javadoc as well. 

The two relevant commits upstream are:

I'll generate a patch for the book and submit it."	defect	closed	normal	8.4	BOOK	SVN	medium	fixed
