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