  31  * DESCRIPTION
  32  *     This test performs checking for
  33  *         command set: ObjectReference
  34  *         command: IsCollected
  35  *     Test checks that debugee accept the command packet and
  36  *     replies with correct reply packet.
  37  *     Also test checks that the returned isCollected value is false
  38  *     because tested object is not garbage collected into debuggee.
  39  *     Test consists of two compoments:
  40  *         debugger: iscollected001
  41  *         debuggee: iscollected001a
  42  *     First, debugger uses nsk.share support classes to launch debuggee
  43  *     and obtain Transport object, that represents JDWP transport channel.
  44  *     Also communication channel (IOPipe) is established between
  45  *     debugger and debuggee to exchange with synchronization signals.
  46  *     Next, debugger obtains from debuggee classID for the tested class
  47  *     and objectID as the value of the class static field.
  48  *     Then, debugger creates command packet for ObjectReference.IsCollected
  49  *     command with the found objectID as an argument, writes packet to
  50  *     the transport channel, and waits for a reply packet.
  51  *     When reply packet is received, debugger parses the packet structure
  52  *     and extracts isCollected boolean value. Also test checks that the
  53  *     extracted isCollected value is false.
  54  *     Finally, debugger sends debuggee signal to quit, waits for it exits
  55  *     and exits too with the proper exit code.
