Have not gone through the javadoc changes in detail yet but plan to, only scanned it just now

On a quick skim of the test, it could use some TLC which you might consider doing now or later.  

It would be really good for future maintainers if there was a comment which introduced each test as to what it was trying to exercise (not just a bug number).  Same with some of the private helper methods.

You probably want to include your bug number in the @bug declaration which starts on line 27

There should be an `@Test` I believe as unless I missed it, this method is not called anywhere else
