Thanks, I'll fix that.

"It" refers to the method as it really doesn't have a use now (these 
methods haven't really been needed since JDK 1.1). However, I see how 
this could be mis-read so I will adjust the wording.

The permissions haven't changed and existing policy files will continue 
to work. Also remember we changed the AWT implementation in JDK 8 to use 
checkPermission directly so the 3 methods aren't used. It's possible 
that there is code somewhere are is invoking these legacy methods 
directly and that was the reason for deprecating it in 8 with the 
wording to make it clear that these methods would be change in the 
future. Also by getting this change done early in JDK 9 then it gives 
every opportunity to flush out issues.
