#!/usr/bin/env jruby
# This code works fine in MRI, but not JRuby. For some strange reason 
# jruby cannot superclass FFI::MemoryPointer or FFI::Buffer and override
# the initialize() method.

require 'ffi'

class SpecialBuffer < FFI::Buffer
  def initialize()
    super(256)
  end
end

p SpecialBuffer.new()

# produces:
# ArgumentError: wrong # of arguments(0 for 1)
#        from ...:in `new'
