I’m experimenting with JRuby on Android. With the jruby 1.1.4 jar, I get this error:
[2008-10-06 17:49:52 - AndroidTst] warning: Ignoring InnerClasses attribute for an anonymous inner class that doesn't come with an associated EnclosingMethod attribute. (This class was probably produced by a broken compiler.)

I’m not seeing the same problem with jruby trunk though.
