This is a demo of an error I am seeing when attempting to access self inside the initialize method of a class

wrapper_test.rb

#! /usr/bin/env jruby

require 'java'

java_import java.util.Date

class Klass
  def initialize
    puts "Hi.  I'd like to see what I look like during initialization.  :)"
    puts "self # => #{self} (#{self.class})"
  end
end

class JavaKlass < Date
  def initialize
    puts "Hi.  I'd like to see what I look like during initialization.  :)"
    puts "self # => #{self} (#{self.class})"
  end
end

class Test
  def initialize
    @a = Klass.new
    @b = JavaKlass.new
  end
end

Test.new if __FILE__ == $0
