Yes, upgrading to the latest 7.4 maintenance release (which if of course always a good idea anyway :)) The log message has been downgraded to FINER in 7.4.3 so should not be a problem anymore.
Maybe off topic a little, but I ll try to be clear and catch you Johannes while you are still in place!
I have problem with CDI add on + Push (Push can not use Websocket protocol with CDI, just long-polling)
When I include CDI add-on, my client debug shows:
207ms Establishing push connection
278ms Push connection closed
281ms Push connection using primary method (websocket) failed. Trying with long-polling
308ms Push connection established using long-polling
Without, transport protocol is websocket and everything is alright.
I couldn’t find solution on other posts on forum with this subject…
Which Vaadin and CDI version are you using? Which server? There are some fundamental issues with CDI and websockets as the CDI spec assumes HTTP (eg. there’s no request scope or session scope with websockets.) Other related technologies such as JAAS are not websocket-compatible either. However, CDI should currently partially work with websockets (ticket
12464 )
