RPC AsyncCallback freezes chrome

Hi, I wrote this in the issue tracker but I was redirected to here.

Found in GWT Release (2.5.1, 2.5.0.rc1)    Encountered on OS / Browser (Win7, Google Chrome):      Detailed description:    Dear folks,    we have a complex and large gwt app with many rpc calls.  In Google Chrome, there are some rpc call that freezes the browser's thread, cpu runs at 13%, and the page does not respond anymore, only closing the page helps. It happens only in Chrome (not in Firefox), and only in production mode with compiled gwt code (it works well in dev mode). The rpc call initiated properly, the server responds some data (data from an Oracle db), but neither of onSuccess nor onFailure is called, but Chrome freezes.  In "Network" tab of Chrome I see the call with status code 200, but the "Preview" and the "Response" tabs are empty despite of the server sends back the data (I see it in a log).        Shortest code snippet which demonstrates issue (please indicate where  actual result differs from expected result):    MxServiceAsync svc = GWT.create(MxService.class);      //fine  svc.frameRPC(nb, new AsyncCallback<NucleusBean>() {    //fine  	public void onFailure(Throwable t) {  		t.printStackTrace();                   //never called  	}  	public void onSuccess(NucleusBean result) {  		System.out.println(result);            //never called  	}  });        Workaround if you have one: NONE

In Fiddler network monitor I can see the response (correct data) from the server (Apache Tomcat).
    ANY help or advise is appreciated!
