Gary D. Gregory commented on IO-719:
------------------------------------
The JRE provides multiple file systems IIRC: file and zip. Why not test with
those? I would expect a test using those two to at least show that the problem
is not specific to jimfs. If you can show a failing test with zip and file then
we can consider a fix. At that point we could consider additional tests with
jimfs but it might not be needed.
> PathUtils.copyDirectory() does not work when source and dest belong to
