Java – debug in GWT 2.7 super development mode. Is stacktrace missing?

I just got from GWT 2.5 1 migrate to 2.7 and use superdev mode for the first time

com.google.gwt.event.shared.UmbrellaException: Exception caught: For input string: "a"
  at fillInStackTrace_0_g$

Onmoduleload is an exception to caching:

GWT.setUncaughtExceptionHandler(new GWT.UncaughtExceptionHandler() {
        @Override
        public void onUncaughtException(Throwable e) {
            GWT.log(e);
        }
    });

How can I get stacktrace? I've tried something like this https://stackoverflow.com/a/24334132/1660637 , but it doesn't work

Solution

Would you like to try adding these to GWT XML file?

<set-property name="compiler.stackMode" value="emulated"/>
<set-configuration-property name="compiler.emulatedStack.recordLineNumbers" value="true"/>
<set-configuration-property name="compiler.emulatedStack.recordFileNames" value="true"/>
