ex:
install ubuntu, install default-jre-headless

run this:

https://gist.github.com/rdp/b25a0483c196c856c33a

require 'java'

class A < javax.swing.JFrame

def initialize _args
super(_args)
end
end

A.new

expected output:

Java::JavaAwt::HeadlessException exception (which is generated with a straight javax.swing.JFrame.new call)

current output:

jruby ArgumentError: Constructor invocation failed: null

it's like the real error message is being masked.

possibly not a high prio, but thought I'd mention it.

gist version runs fine on 9K (exits), while your piece here fails as expected with a

ArgumentError: wrong number of arguments (0 for 1)

... which is expected since the argument is not provided.

assuming this is resolved with the updated JI overload method matching, for 1.7.x is won't fix.
