I looked through the javadoc for the updated/new methods and it mostly 
looks good.

I think URLDecoder.decode methods should have @throws 
IllegalArgumentException. I realize it's implementation specific as to 
whether IAE is thrown with bad input but given that the RI does throw 
IAE then consumers of the API should be prepared for it. The @implNote 
can stay and probably should be copied into the legacy decode method too.

One of the new constructors on Scanner needs @since 10.
