Description

When you attempt to copy a directory and the destination directory is inside the source directory an inifinite loop occurs in the copyDirectory causing Commons-IO to create a folder w/o stopping until its reaches OS limitation.

This code will recreate the bug:

FileUtils.copyDirectory(new File("C:\\temp\\test-io\\a
."), new File("C:\\temp\\test-io\\a
." + File.separator + new Date().getTime()));

Make sure C:\temp\test-io\a exists
