      Description

      On Wildfly10, we are experiencing intermittent problems where on server startup, an @Timeout annotated method can be executed hundreds of times in a second (log below). Going through the references to the @Timeout methods and the @Scheduled methods, all scheduled methods are set to be non-persistent (ex: timerConfig.setPersistent(false), persistent=false) so we don't know how this could occur. It is not consistent and our only solution has been to kill the Wildfly10 server process and restart.
