Description

I called this method, but the target directory was not deleted.

The source of this method is as follows.
----------
private static void deleteDirectoryOnExit(File directory) throws IOException {
if (!directory.exists())

{ return; }

cleanDirectoryOnExit(directory);
directory.deleteOnExit();
}
----------
In other words, this method calls "java.io.File#deleteOnExit" in order of "grandchildren -> children -> parent" for files of the target directory hierarchy.

There is following mention in javadoc of "java.io.File#deleteOnExit".
----------
Files (or directories) are deleted in the reverse order that they are registered.
----------

Therefore, I think the calling order of "java.io.File#deleteOnExit" should be reverse.

How will be it?
