8062632: (fs spec) Package description could be clearer on the cases where NPE is thrown

[Alan Bateman]

I need a Reviewer for some trivial updates to the javadoc to address 
these issues:

8062632: (fs spec) Package description could be clearer on the cases 
where NPE is thrown
8062553: (fs spec) Files.write and newBufferedWriter methods missing 
@throws IAE

The first is just a two word adjustment to the spec on when 
NullPointerException is thrown. The second is that the write and 
newBufferedWriter methods are missing the @throws IllegalArgument.

Thanks,
