I only have time to look at the changes to FileSystems.java right now.

One nit in the wording is in "in exactly the same manner as the 
newFileSystem ..."  - the word "method" has been dropped from the 
original text. Looks like the same thing shows up in several places so 
it would be good to fix those.

Minor formatting nit on L472 where the "throws IOException" doesn't need 
to be on its own line.
