I haven't seen this come up before in a scan like this, thanks for sharing!
This is due to the compiler, but rather than obfuscation, this is due to the compiler solving for a constant value rather than doing the math at runtime. This same constant appears in the GWT showcase as well, at https://samples.gwtproject.org/samples/Showcase/Showcase.html in the https://samples.gwtproject.org/samples/Showcase/showcase/deferredjs/5F20F7F6874DB82B437E6EA4319E4E9B/47.cache.js file. function Hmc(a,b,c,d,e,f){Gmc();this.a=e;Th(a,Dwc(b,c,d,e,f));a.db==-1?(Sbc(),Idc(a.hb,133333119|(a.hb.__eventBits||0))):(a.db|=133333119)} This is slightly different from yours, and not just in the obfuscation - I suspect that you have emulated stack traces enabled, which should allow you to check the value of the NWl and RWk constants to confirm - they should be the "stack trace element" information, like class+method name, line number etc. In this case, that particular line comes from Image.java's constructor. That calls the constructor of the inner class UnclippedState, which has these lines: UnclippedState(Image image) { image.replaceElement(Document.get().createImageElement()); // We are working around an IE race condition that can make the image // incorrectly cache itself if the load event is assigned at the same time // as the image is added to the dom. Event.sinkEvents(image.getElement(), Event.ONLOAD); // Todo(ecc) this could be more efficient overall. image.sinkEvents(Event.ONCLICK | Event.ONDBLCLICK | Event.MOUSEEVENTS | Event.ONLOAD | Event.ONERROR | Event.ONMOUSEWHEEL | Event.TOUCHEVENTS | Event.GESTUREEVENTS); } That chained | expression results in the number you're seeing. Then, that value is passed to Widget.sinkEvents(), which looks like this: @Override public void sinkEvents(int eventBitsToAdd) { if (isOrWasAttached()) { super.sinkEvents(eventBitsToAdd); } else { eventsToSink |= eventBitsToAdd; } } The isOrWasAttached() call is a comparison of a field to -1, and a ternary is used instead of an if/else for this: a.db==-1 ? (Sbc(),Idc(a.hb,133333119|(a.hb.__eventBits||0))): (a.db|=133333119) Now it becomes clear that "this.eventsToSink" is "a.db", and "eventBitsToAdd" is the constant int 133333119.
