There are a lot of niceties to JRuby's Java integration -- for
example, a method called #isSomePredicate is also accessible as
#some_predicate?, and (at least in 1.1) you can use a Ruby block
in lieu of a terminal argument whose type is any single-method
interface (e.g. Runnable).  Java collections also implement
Ruby enumerable and so on.

Not that there aren't rough spots to work out yet, but we're
making a concerted effort to have Java libraries feel as "Ruby" as
possible.
