        If the Java uses URLConnections, and the port number is
        greater than 1024, nothing needs to be done. If it is
        less than 1024, you need to consider whether it safe to
        let it through and, if so, change the list of safe ports.

        If the Java uses TCP connections directly, you need to
        configure your firewall to let the port through and Squid
        will in no way be involved.
