This seems to have been fixed in 6.2.0 RC2, I have not had the error at all on 6.2.0 RC2, I then spend a bit of time finding a reliable sequence of events that caused the error and found a way to reproduce consistently on 6.1.2 following a specific series of login/logout requests:
In the same browser window: Login to system A. Login to system B. Logout System B. Login to system A. Logout System A. Login System B - results in error. Above resulted in the error on every attempt, I then replaced the 6.1.2 cas.war file with 6.2.0 RC2 no other changes made to config etc and repeated above and did not get the error. -- - Website: https://apereo.github.io/cas - Gitter Chatroom: https://gitter.im/apereo/cas - List Guidelines: https://goo.gl/1VRrw7 - Contributions: https://goo.gl/mh7qDG --- You received this message because you are subscribed to the Google Groups "CAS Community" group.
