[GWT 2.8 SHNAPSHOT] missing stack trace for 'Should only call onDetach when the widget is attached to the browser's document'

Hi all,
I wonder if anyone can help me figure out what is causing this - I am getting java.lang.IllegalStateException: Should only call onDetach when the widget is attached to the browser's document . See below. I suspect this is a GWT exception of some kind, but the stack trace is obfuscated and I can not figure out where the problem is. I tried installing my exception handler with no success - the stack trace is still useless:

 Console.log("Exception logger INSTALLED!!!");
        GWT.setUncaughtExceptionHandler(e -> {
            GWT.log("Unhandled exception", e);

This is happening with Errai 4 SNAPSHOT randomly, but if I figure out the stack trace I can get better understanding of what is going on. How do I get the stack trace ? How do I verify that the gwt Code server has all source maps it needs???
