  31  * DESCRIPTION
  32  *     This test performs checking for
  33  *         command set: ObjectReference
  34  *         command: SetValues
  35  *     Test checks that debugee accept the command packet and
  36  *     replies with correct reply packet. Also test checks that
  37  *     the values are correctly set to debuggee class fields.
  38  *     Test consists of two compoments:
  39  *         debugger: setvalues001
  40  *         debuggee: setvalues001a
  41  *     To set values to the static fields of the tested class
  42  *     and check that they are set correctly, test defines
  43  *     following classes into debuggee VM:
  44  *         OriginalValuesClass - class with original values of static fields
  45  *         TargetValuesClass - class with target values of static fields
  46  *         TestedClass - tested class with tested fields to set values to
  47  *         ObjectClass - class with one static field for the tested object
  48  *     First, debugger uses nsk.share support classes to launch debuggee
  49  *     and obtain Transport object, that represents JDWP transport channel.
  50  *     Also communication channel (IOPipe) is established between
  51  *     debugger and debuggee to exchange with synchronization messages.
  52  *     Next, debugger obtains classIDs for the tested class and class with
  53  *     the target values from debugee. It obtains also fieldIDs for thess
  54  *     classese and target values of the fields. It obtains also objectID
  55  *     as the value of a static field of the object class.
  56  *     Then, debugger creates command packet for SetValues command with the
  57  *     found objectID and list of fieldIDs as arguments, writes packet
  58  *     to the transport channel, and waits for a reply packet.
  59  *     When reply packet is received, debugger parses the packet structure
  60  *     and and checks that there is no data in the reply packet.
  61  *     Then debugger sends signal RUN to debuggee to ask it to verify
  62  *     new fields values of tested class. Debuggee compares these values
  63  *     with the original and target values and sends ERROR signal
  64  *     to debugger if the values was not set correctly.
  65  *     Finally, debugger sends debuggee signal to quit, waits for it exits
  66  *     and exits too with the proper exit code.
