Need reviewer for 6876541: (file) Files.walkFileTree(...): no SecurityException if read access to the starting file is denied

[Alan Bateman]

I need a reviewer for this faux pas in Files.walkFileTree. 
SecurityException should be thrown if access to the starting file is 
denied by the security manager. Instead, the exception is silently 
consumed and the starting file ignored (ie: walkFileTree does nothing). 
A secondary issue (Windows only) arises where a security manager allows 
access to a directory but not to the all entries in that directory. Such 
entries should be skipped but non-directory entries are still notified 
to the FileVisitor. The webrev is here:

Thanks,
Alan.
