May be related to un-closed files. Just possibly related to #2307.

It seems shutil.copytree is broken on Windows. See #2474.

My observation of #2314 is that setReadonly() reports failure when the target is a directory. It seems this is because the simple DOS read-only flag on a directory doesn't mean what Java means by read-only, it means "don't delete me". So making a directory read-only in the Java sense cannot succeed. See:

http://bugs.java.com/bugdatabase/view_bug.do?bug_id=6728842

I think is at least a contributory factor in #2474 as Pekka suggests.

A proper solution involves ACLs. For now, ignoring the read-only for directories seems most consistent. And it makes the regression test pass.

Fixed ages ago in https://hg.python.org/jython/rev/c168765aae66 with no come-back.
