    Description

      The behavior of DatagramSocket / DatagramChannel send method when the target address is specified to port 0 appears to be system dependent:

      on Linux / macOS: an IOException is thrown.
      on Windows / Solaris: no exception is thrown.

      Whether the spec and implementation should be changed to always throw IllegalArgumentException instead should be examined.
