You could try using an UncaughtExceptionHandler. Assign your
implementation in onModuleLoad() by
GWT.setUncaughtExceptionHandler(...);
Then use a DeferredCommand for calling your actual entry point method:
DeferredCommand.addCommand(new Command() {
public void execute() {
yourEntryPointMethod();
}
});
You can use the UncaughtExceptionHandler to print stack trace for
example.
See
http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/core/client/GWT.UncaughtExceptionHandler.html
and
