GWT Reflection with deferred bindings GAE works in Firefox, not chrome, IE

Question

i have a problem with deferred bindings.

i created it like in this Blog: http://programmatica.blogspot.com/2007/10/classfornamefullyqualifiedclassnamenewi.html

My code crashed at "GWT.create". But only when i run it on Google App Engine, and only in IE and Chrome. Code works correctly local in every browser and online on GAE in Firefox.

Logger logger = Logger.getLogger("AMsController");
               logger.log(Level.INFO, "start reflect");
final IPresenterFactory factory = (IPresenterFactory)     
GWT.create(IReflectiveFactory.class);
logger.log(Level.INFO, "1");
IDynamicPresenter p =  factory.newInstance("ch.zhaw.ams.module.football.sfv.news.client.presenter.NewsPresenter");

i don't have any error messages, but if I anlyse the cache.html for IE and for Firefox they are different.

it thows a ClassCast exception in IE, but not in firefox

Actually i'm trining to get the stack trace, but i don't get it on client side and no log entry on Google App Engine developer console. — Sam, May 03 '12 at 20:53
If I compile the code without runtime class-casting the code works on App Engine as well as on local server — Sam, May 03 '12 at 21:10

I compiled it without Runtime Class-Casting - than it works!

problem was ClassCasting in IE-cache.html file

-XdisableCastChecking as Compiler Flag
