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_missing_jruby_home.rb
    path of file: ./repos/jruby/test/jruby
    
    the code of the file until where you have to start completion: require 'test/unit'

class TestMissingJRubyHome < Test::Unit::TestCase

  def setup; require 'java'
    @jruby_home = java.lang.System.get_property('jruby.home')
    java.lang.System.clear_property('jruby.home')
  end

  def tea
    
  def test_missing_jruby_home
    runtime = org.jruby.Ruby.new_instance
    assert_equal('[0, 1, 2]', runtime.eval_scriptlet('3.times.to_a.inspect'))
    runtime.eval_scriptlet('begin require "rbconfig"; rescue LoadError; end')
    # NOTE: used to work at some point when JRuby's load service had special handling
    # for loading of libraries, such as rbconfig, which are implemented natively.
    #
    # This was changed in 9.2.6 (due bootsnap) for every stdlib library to have a .rb
    # @see https://github.com/jruby/jruby/issues/6362
