    Description

      The `MulticastSocket` methods `getOption` and `setOption` have been changed to conform to the behavior described in the `StandardSocketOptions.IP_MULTICAST_LOOP` specification.
      `MulticastSocket.getOption(StandardSocketOptions.IP_MULTICAST_LOOP)` now returns true if loopback mode is enabled. Setting `MulticastSocket.setOption(StandardSocketOptions.IP_MULTICAST_LOOP, true)` enables loopback mode.
