+/**
+ *  Summary
+ *  -------
+ *
+ *  Define a lightweight network protocol for discovering running and
+ *  manageable Java processes within a network subnet.
+ *
+ *
+ * Description
+ * -----------
+ *
+ * The protocol is lightweight multicast based, and works like a beacon,
+ * broadcasting the JMXService URL needed to connect to the external JMX
+ * agent if an application is started with appropriate parameters.
+ *
+ * The payload is structured like this:
+ *
+ *  4 bytes JDP magic (0xC0FFEE42)
+ *  2 bytes JDP protocol version (1)
+ *  2 bytes size of the next entry
+ *      x bytes next entry (UTF-8 encoded)
+ *  2 bytes size of next entry
+ *    ...   Rinse and repeat...
+ *
+ * The payload will be parsed as even entries being keys, odd entries being
+ * values.
+ *
+ * The standard JDP packet contains four entries:
+ *
+ * - `DISCOVERABLE_SESSION_UUID` -- Unique id of the instance; this id changes every time
+ *    the discovery protocol starts and stops
+ *
+ * - `MAIN_CLASS` -- The value of the `sun.java.command` property
+ *
+ * - `JMX_SERVICE_URL` -- The URL to connect to the JMX agent
+ *
+ * - `INSTANCE_NAME` -- The user-provided name of the running instance
+ *
+ * The protocol sends packets to 224.0.23.178:7095 by default.
+ *
+ * The protocol uses system properties to control it's behaviour:
+ * - `com.sun.management.jdp.port` -- override default port
+ *
+ * - `com.sun.management.jdp.address` -- override default address
+ *
+ * - `com.sun.management.jmxremote.autodiscovery` -- whether we should start autodiscovery or
+ * not. Autodiscovery starts if and only if following conditions are met: (autodiscovery is
+ * true OR (autodiscovery is not set AND jdp.port is set))
+ *
+ * - `com.sun.management.jdp.ttl`         -- set ttl for broadcast packet, default is 1
+ * - `com.sun.management.jdp.pause`       -- set broadcast interval in seconds default is 5
+ * - `com.sun.management.jdp.source_addr` -- an address of interface to use for broadcast
