When:

• I try to login to tasklist by browsing to localhost:8080/app/tasklist/ or localhost:8080/app/tasklist/default/

Then:

• A "java.lang.IllegalStateException: Cannot create a session after the response has been committed" is raised and every action in the tasklist brings me back to login page

Workaround: Logging into welcome and cockpit works, so one can log in there and then switch to tasklist.

It was working in 7.10.x
