UDP Transport connector listens on a random port number

      Description

      The broker listens on a random UDP port number instead of the one configure in the URI. The port number changes each time the broker is restarted. However, the management console indicates that the broker's listening on the configured port number while it is not the case (netstat shows another UDP port number). The reason is that (as seen in the following block) the UdpTransport constructor does not assign "this.port" from remoteLocation but only reads the address and leaves "this.port" to be zero. Subsequently, Java API picks any available port number when it is creating the DatagraSocket. The solution is to add this line: "this.port = remoteLocation.getPort();" to the following constructor as seen in the accompanying patch.

      public UdpTransport(OpenWireFormat wireFormat, URI remoteLocation) throws UnknownHostException, IOException {
      this(wireFormat);
      this.targetAddress = createAddress(remoteLocation);
      description = remoteLocation.toString() + "@";
      }
