How to debug GWT application on Eclipse

Hi GWT community. 
I am trying GWT since yesterday, and I'm following the first app tutorial on gwt official.
I'm at the debugging section and i can't figure it out to debug my code in eclipse. 

I followed each line of this tutorial, so this is what I've done : 
- Installed the last eclipse version (Version: Neon Release (4.6.0))
- Installed GWT pluggin for eclipse + sdk : Plugin for Eclipse 4.5 (Mars)
- Created the first app Stockwatcher from the eclipse pluggin (I didn't used webAppCreator or maven atm)
- Built my UI code

Until there, all is working fine. I use the run as Web Application (GWT Super Dev Mode) in eclipse and I see my app working in chrome at the

The problem I have now during the debugging part is, when I put some breakpoint in my code, I relaunched my app in the same mode (GWT Super Dev Mode) but my code never stopped on my breakpoint. So I tried to launch it with Debug as Web Application (GWT Super Dev Mode)... Same here : No stop on breakpoint. So I tried an other mode : Run/Debug as Web Application (GWT Classic Dev Mode), my generated url changed to But when I launched it in my chrome / FF, I got this popup : "Couldn't load stockwatcher from Supder Dev Mode server at Please make sure this server is ready. Do you want to try again?"

What I did wrong ?

Thanks for your tips ;)
