request.getSession(true) - returns session = null

Vaadin 6 / 7 / 8

My code:

@Theme("valo") public class DashboardApplication extends UI { @Override public void init(VaadinRequest request) { final HttpServletRequest req = ((VaadinServletRequest) VaadinService.getCurrent().getCurrentRequest()).getHttpServletRequest(); final HttpServletResponse res = ((VaadinServletResponse) VaadinService.getCurrentResponse()).getHttpServletResponse(); ... HttpSession session = req.getSession(true); ClientContext context = new ClientContext(); session.setAttribute(CommonConst.CLIENT_CONTEXT, context); here session = null.
if debug my app by putting breakpoint on line (8) - all ok! why?

thanks

Maybe you are using a broken Servlet container (webserver)?

All good here, using Vaadin 7.6.8 and Tomcat v8.0 running on OSX 10.11.6.
Even when not debugging.

Best,
