I have the same problem when deploying a portal page with some JSF portlet. The same page, with the JSF portlet, used to work with 2.4.1SP1. I am migrating from 2.4 to 2.6, and as far as I remember, it worked just before I added a new jsf portlet in this page. But not absolutely sure I did the check on that portlet before to go on with the new one. I use MyFace 1.1.4. I keep searching.
