Files.walkFileTree

[Alan Bateman]

Files.walkFileTree has accumulated a few issues that I plan to fix soon. 
Earlier this year  Rémi observed that the FileVisitor methods can't 
throw a IOException and jave propagate it to the caller of 
Files.walkFileTree. John Hendrikx pointed out that the preVisitDirectory 
should be invoked with the attributes of the directory. The other one is 
Jon Gibbon's observation that using the maxDepth parameter requires 
opening the directory at maxDepth+1. All of these issues require 
updating the javadoc so I'd like to do them in one batch. Does anyone 
have any other issues with Files.walkFileTree/FileVisitor that need to 
be fixed while in the area?

Thanks,

-Alan.
