If they are in pure ruby 1.8 and have no dependency to C-Extensions
(even through gems), chances are very high[1] that they run as
expected.

Otherwise, it's a question whether those extensions are available
in a Java Version or through FFI (Foreign Function Interface). FFI
is pretty uncommon at the moment, but there is quite a bunch of
gems that implement their extensions both for MRI and JRuby.
