Showcase 5.3 and Glassfish 4.1 issue

[CORSIC]

Hello,
i'm trying to deploy and use the showcase 5.3 on glassfish 4.1 server.
The push cases are not working on it (nothing appens when clicking on the "notify" case.

The same showcase deployed on a 4.0 glassfish server works.

Is there a know issue and fix for it ?

Thanks
Best regards,

Same problems when using a custom app based on primefaces, and other filters/servlets.

put <async-support>true</async-suport>
on all filters and servlets used in the App (web.xml).

Still not working completly well. Push is firing, but corrupts pages where <p:socket> is declared.
