The application is loading in the browser, however it is throwing exceptions which says
11:59:49.770 [ERROR] [loginform] Uncaught exception escaped
com.google.gwt.event.shared.UmbrellaException: One or more exceptions
caught, see full set in UmbrellaException#getCauses
at com.google.gwt.event.shared.HandlerManager.fireEvent(HandlerManager.java:129)

What is the cause and how to resolve this?
You are missing the interesting part. Create an uncaught exception-handler,
like in this question.
update:
As you can see here: GWT/JAVA Uncaught exception escaped
The Stacktrace should be longer. There is a root-cause atatched to the Umbrella-Exception.
