/**
 * Test for the control of
 *
 *      Interface:      com.sun.jdi.connect.Connector.Argument
 *      Method:         public java.lang.String value()
 *      Assertion:      "Returns the current value of the argument."
 *
 *
 *      Comments:       The test aims on the concrete Sun's JDI
 *                      reference implementations. It uses
 *                      com.sun.jdi.RawCommandLineLaunch connector and its
 *                      "command" argument.
 *                      The test sets up the new "command" argument
 *                      value and then checks that new value remains previously
 *                      after connection establishing with debugee VM and
 *                      after debugee VM finishing.
