Yes, you can. Just make sure to install OpenJRE/OpenJDK to its own
directory, and specify this version whenever you want to use JRuby.

Then, you can test if the Oracle version makes any of your other apps
fail, before migrating over (if you want to).

You should also post JRuby specific questions one mailinglist over on
JRuby-user. There's the experts who can help you with both Java and
JRuby issues. :)

(Ah, how soon!) they forget
When I've moved on to some other place,
There may be one or two,
When I've played and passed through,
Who'll remember my song or my face.
