Hi Jason,

I guess overriding and marking the CharBuffer method final for
consistency wouldn't hurt. Except I probably need to pass this through
another CSR review.

Also added test cases for char[] and String-based CharBuffers:

Claes,

I would think CharBuffer would require some testing in your test cases too.  
Also it looks like some of the CharSequence methods in CharBuffer are declared 
final.  Not sure what is appropriate here as far as CharBuffer::isEmpty 
modifiers are concerned.

Hi Roger,

sure, added Emptiness.java with a few sanity tests.

Hi Claes,

Though it does not look like it could be any simpler, there should
probably be a test.
Checking consistency with the existing implementations of
CharSequence.length()
and a custom subtype.

Thanks, Roger
