We are using bonita BonitaBPMSubscription-7.2.2-Tomcat-7.0.67 version and one of our bonita test server is on Linux / RHES5.0 server. Today there was a need to restart my tomcat. Post restarting the server I am getting "org.bonitasoft.console.common.server.auth.AuthenticationManagerNotFoundException: The AuthenticationManager implementation null does not exist!".
Today absolutely there is no code change. Only restarted the server. This very unpredictable behavior observed from bonita.
