It is a OS mechanism and i think it is good that java reveals all information also available with native access (i.e. if you have no 'x' permission on a dir you cannot enter it but you can see it (as long asmyou have read permission on the parent).

That's right and I think this question is about the scenario where some 
of the file system is not accessible. With Files.walkFileTree then you 
provide a FileVisitor that can deal with exceptions and control which 
parts of the file tree are visited. The newer walk/find methods don't so 
it would require introducing a new API. It's come up before, and is easy 
to do, just not clear that we want to introduce yet further variations.
