[IO][PATCH] Infinite loop on FileUtils.copyDirectory when the destination 
directory is within the source directory
------------------------------------------------------------------------------------------------------------------

                 Key: IO-141
                 URL: https://issues.apache.org/jira/browse/IO-141
             Project: Commons IO
          Issue Type: Bug
          Components: Utilities
    Affects Versions: 1.3.2
         Environment: Win XP
            Reporter: Mark Bryan Yu
            Priority: Critical


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()));
