UDP broadcast does not work to loopback device without network connection?

    While developing some Java tools that use UDP broadcasting, I found
    that my laptop will not broadcast packets back to the loopback device
    *IF* I do not have a network connection (IP address assigned to one of
    my interfaces) even if i turn on broadcasting and share ports. Does
    anyone know if this is expected (or maybe undefined?) behaviour in
    networking in general, a Java specific issue, a bug, or some other
    option I have not listed?

    Thanks!
