  27  * A test service for use in the inetd/System.inheritedChannel unit
  28  * tests.
  29  *
  30  * The test checks that the channel returned by System.inheritiedChannel
  31  * is in blocking mode and is bound. In addition, in the case of a
  32  * SocketChannel checks that the socket is connected.
  33  *
  34  * The test service is launched with an argument that is the reply port.
  35  * This reply port is used as an out-of-band connection to the unit test
  36  * so that the test status can be reported. When the test completes it
  37  * establishes a TCP connection to the port and sends a PASSED/FAILED
  38  * message to indicate the test result.
