  31  * DESCRIPTION
  32  *     This test performs checking for
  33  *         command set: ThreadGroupReference
  34  *         command: Children
  35  *     Test checks that debugee accepts command and replies
  36  *     with correct reply packet.
  37  *     First, test launches debuggee VM using support classes
  38  *     and connects to it.
  39  *     Then test queries debugee VM for ThreadGroupReferenceIDs
  40  *     of all top level thread groups.
  41  *     Then test sends Children command for each ThreadGroupReferenceID
  42  *     and waits for a reply packet.
  43  *     Test checks if the each received reply packet has proper
  44  *     structure and extract childs info of the queried thread group.
  45  *     After JDWP command has been tested, test sends debugee VM
  46  *     signal to quit, waits for debugee exits and exits too
  47  *     with a proper exit code.
