Declare method signatures for ruby methods and use become_java! on the Ruby class?

Wow! example?

Booo! jruby sucks!

1.1.6 fwiw

lib/temp_subscriber.rb:9: undefined method `add_method_signature' for TempSubscriber:Class (NoMethodError)
from lib/temp_subscriber.rb:5:in `require'
from cep.rb:5



require 'java'
require 'jruby/core_ext'
class TempSubscriber
  def update(f, cid)
    puts "avg temp is #{f} for customer #{cid}. woo!"
  end
end
TempSubscriber.add_method_signature("update", [java.lang.Void::TYPE, java.lang.Float::TYPE, java.lang.String.java_class])
TempSubscriber.become_java!

durr. 1.1.6 < 1.6.*

hmm. out of date examples? does java_signature work? what about jrubyc? see http://github.com/nicksieger/java-from-ruby-examples/blob/master/compile/compile.rb for example
