[keycloak-dev] Spurious logouts in AdminConsole with 2.2.0.Final (current master)

Hello group, since I upgraded to our Keycloak instance to 2.2.0.Final I see spourious logouts form the admin-console while browsing the UI and editing stuff... I experience the same with the current master. I couldn't yet narrow it down but having to login every ~ 5 mins is really unpleasant - I also got logged out within 30sec after login when I wanted to add a new protocol mapper to a client. Has anyone experienced the same? Cheers, Thomas
