If we wanted to I could test it and say here, it works, use it.   It is a much more difficult process (and usually combinatorially impossible) to do that with every version of every library that someone might attempt to run XMLVM against. 

I agree with that.
As I said in the looong message, we can really have for our own use a "private" lib folder with all recommended lbrary versions - and leave compatibility chaos to the system packages.
What I don't like is to have embedded OpenJDK (and much more) inside the JAR, which needed to be double-unzipped every time.
What I am proposing actually is what every other project is doing: go from a monolithic to a modular system - even if the modules are "private", and "independent" from the "system libraries" of the same name.

Size, probably not. But speed is. And it is here every time you compile a program. Don't tell me you haven't experienced it?

See above ;)
