You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: test_java_extension.rb
    path of file: ./repos/jruby/test/jruby
    
    the code of the file until where you have to start completion: require 'test/unit'
require 'test/jruby/test_helper'
require 'java'

class TestJavaExtension < Test::Unit::TestCase
  include TestHelper

  class TestParent < org.jruby.test.Parent
    attr_accessor :result
    def run(a)
      @result = "TEST PARENT: #{a}"
    end
  end

  java_import org.jruby.test.Worker

  def test_overriding_method_in_java_s
    
  def test_synchronized_method_available
    # FIXME: this doesn't actually test that we're successfully synchronizing
    obj = java.lang.Object.new
    result = nil
    assert_nothing_raised { result = obj.synchronized { "foo" } }
    assert_equal("foo", result)

    begin
      obj.wait 1
    rescue java.lang.IllegalMonitorStateException => e
      assert e
    else
      fail "java.lang.IllegalMonitorStateException was not thrown"
    end

    assert_nothing_raised { obj.synchronized { obj.wait 1 } }
  end
