I don't have time to detail this just now but you can specify a DACL (as 
a FileAttribute<List<AclEntry>>) to Files.createDirectory so that the 
directory is created with an initial DACL that denies access. 
Alternatively, you can change the DACL of an existing directory. Yes, a 
bit complicated to setup. I don't think it would be too much of a 
surprise for this sub-test to only execute on platforms that support 
POSIX file permissions (I think some of the tests check this already).
