Jrubyfx apparently causes issues with ruby-debug-ids

gistfile1.txt

Note: code below was used to check out 2.0 named argument support in jruby including JetBrains debug support for jruby in 2.0 mode. If the second require is commented out the code will run without issue

code:
______________________________________________________________________________________
require 'java'
require 'jrubyfx'
#require 'rest-client'

class Hash
  def at key, value_if_absent: nil
		((v = self[key]).nil?) ? (self[key] = value_if_absent) : v

	end
end

h = {rob: 'php_dude'}
puts "rob is: #{h[:rob]}"
puts "robert is: #{h[:robert]}"
puts "now robert is still: #{h.at :robert}"
puts "but rob  is still: #{h.at :rob}"
puts "now robert is: #{h.at :robert ,value_if_absent: 'maybe a Ruby dude someday'}"
puts h
