Well, I'm sure Java has all sorts of other goodies people would like to use.
There is one big gotcha (not counting the underlying implementation and
reliability problems of a JRuby): you often have to learn enough about Java and
spend enough time thinking like Java (especially when it comes to debugging) that
you might as well do the stuff in Java in the first place.

There are quite a few xxxx languages with Jxxxx systems, but AFAIK, non of them
has flourished, even though JPython and JTcl seem to be working tolerably well.
Other approaches like JPL (Java Perl Lingo) seem to be floundering forward at a
snail's pace. Hopefully programming language interfaces that make use of Java's
variously newer, intended, and higher-level interoperability capabilities will
fare better.
