"""
Try importing from a jar after sys.path.append(jar)

This nails down a bug reported here:
    http://sourceforge.net/mailarchive/message.php?msg_id=14088259
which only occurred on systems where java.io.File.separatorChar is not a forward slash ('/')
   
since - at the moment - jython modules hide java packages with the same name from import,
use a unique java package name for the sake of this test
