Fixed Ruby tests for JRuby 1.7

This makes a couple of changes to fix the tests for JRuby 1.7:
- Avoid using assert_false since that assertion seems not to exist in
  older versions
- Disable a test related to respond_to? for JRuby. It's hard to tell
  what is going wrong here but it looks like probably a JRuby bug that
  has been fixed in more recent versions.
