The apparent popularity of Groovy disturbs me, for fear of overhyping
and the fact I wish their JSR a speedy death. Then again, I don't give
much credit to blog polls, especially ones that are instant cues for a
programming language flamewar. Last time I remember, it was a certain
Mr. Spolsky that was being accused of trolling for hits by doing more or
less that.

Wishing no ill fortune to the JRuby folks, I voted for BeanShell on that
one for rational reasons. The role I see for scripting the JVM is in
things usually more people on the team and later maintainers will change
(involved configuration, rules in business rule engines), and making
those easily understood and modified by people you hire to work on a
Java app (read: people who know mostly Java) is paramount. (If you
wouldn't use a scripting language on a part of the app you expect to
change often, where then?).

JRuby has its place, but IMO not really in Java development per se -
more along the lines of doing Ruby development while being able to
leverage Java-only libraries. If it only delivers that, the project has
very high value. It's a somewhat subtle distinction, but until now, the
latter wasn't an itch I needed scratching, so it's also not where my
vote is going.

(Disclaimer: Anyone proposing anything but Java be used to actually
implement some library / framework to be consumed by other people from
Java deserves being handled by the nearest rusty fork. I'm a
multilanguage purist, keep to each its advantages.)
