 * After launching a debuggee, a debugger gets its VirtualMachine<BR>
 * object (vm), invokes the method vm.exit(testedReturnCode);   <BR>
 * and is waiting for the debuggee to finish and to return      <BR>
 * its exit code which should be testedReturnCode               <BR>
 * if debuggee's main thread death exception is not thrown.     <BR>
 * If the thread death exception is do thrown                   <BR>
 * the exit code is FAILED.                                     <BR>
