function $onResponseReceived in generated jsp uses 100% cpu.

function $onResponseReceived(this$static, response){
  var $e0, caught, e, encodedResponse, result, statusCode;

    }
     else if (encodedResponse.indexOf('//EX') == 0) {

    }
     else {
      caught = $InvocationException(new InvocationException(),

    }
  }
   catch ($e0) {
    $e0 = caught_0($e0);
    if (instanceOf($e0, 16)) {
      caught = $IncompatibleRemoteServiceException(new
IncompatibleRemoteServiceException());
    }
     else if (instanceOf($e0, 140)) {
      e = $e0;
      caught = e;
    }
     else 
      throw $e0;
  }
   finally {
    !!$stats && $stats($moduleName, 'rpc', this$static.methodName + ':' +
this$static.requestId + ':responseDeserialized',
timeStat(this$static.methodName, this$static.requestId));
  }
  try {
    if (!caught) {
      this$static.callback.onSuccess(result);
    }
     else {
      this$static.callback.onFailure(caught);
    }
  }
   finally {
    !!$stats && $stats($moduleName, 'rpc', this$static.methodName + ':' +
this$static.requestId + ':responseCallbackDone',
timeStat(this$static.methodName, this$static.requestId));
  }
}

Above javascript code get generated with the var $gwt_version = "1.5.0";

!!$stats && $stats($moduleName, 'rpc', this$static.methodName + ':' +
this$static.requestId + ':responseCallbackDone',
timeStat(this$static.methodName, this$static.requestId));

Above line takes 100% CPU resources. Why that is?

What is the expected output? What do you see instead?
It's should not use 100% CPU.

What version of the product are you using? On what operating system?
var $gwt_version = "1.5.0"
OS:XP
Browser: IE6

Please provide any additional information below.
I are trying to just move the node up or down in a tree and when above
function call uses 100% CPU. This is very high severity issue for us.

The test case runs much faster, less than 5 seconds in Google Chrome and/or 
Firefox
as compared to 45 seconds when using Internet Explorer 6.0 or 7.0. 
In case someone is looking for alternative.

Thank you
