That looks much better.

One case that is still a bit awkward is where there are insufficient 
bits remaining in the source buffer, say when you are consuming from a 
channel and reading a chunk at a time. The decode(ByteBuffer, 
ByteBuffer) method really needs a boolean to indicate to the decoder if 
it capable of providing more bits. I guess it's too late to add that now.

As regards the javadoc updates then a small typo on L660 (=> "is a 
padding character"). On L849, I think I would drop "current".  Do you 
think decode(ByteBuffer) needs a sentence to make it clear that the 
input buffer's position may be advanced even if an exception is thrown?

On the test then it looks like there isn't any coverage to check the 
output buffer's position has been advanced. Otherwise looks fine.
