Hello, I have installed Gluu server 4.1.1 and everything works as expected apart from a very strange log error which keeps filling up the logs. I am not using fido, the idp is setup in a very basic fashion and has ldap_authentication method as its default method and the basic_lock script enabled thats all. Below is the error which keeps occuring i have restarted the box and all services. The oxauth.log has the following after i restarted the service. ``` 2020-06-15 19:39:28,750 INFO [Thread-1] [org.gluu.oxauth.service.AppInitializer] (AppInitializer.java:640) - Stopping services and closing DB connections at server shutdown... 2020-06-15 19:39:28,760 INFO [Thread-1] [org.quartz.core.QuartzScheduler] (QuartzScheduler.java:666) - Scheduler oxAuthScheduler_$_NON_CLUSTERED shutting down. 2020-06-15 19:39:28,760 INFO [Thread-1] [org.quartz.core.QuartzScheduler] (QuartzScheduler.java:585) - Scheduler oxAuthScheduler_$_NON_CLUSTERED paused. 2020-06-15 19:39:28,761 INFO [Thread-1] [org.quartz.core.QuartzScheduler] (QuartzScheduler.java:740) - Scheduler oxAuthScheduler_$_NON_CLUSTERED shutdown complete. 2020-06-15 19:39:28,761 INFO [Thread-1] [org.gluu.service.timer.QuartzSchedulerManager] (QuartzSchedulerManager.java:150) - Quartz scheduler manager destroyed 2020-06-15 19:39:35,709 INFO [main] [org.jboss.weld.environment.servlet.EnhancedListener] (EnhancedListener.java:58) - WELD-ENV-001008: Initialize Weld using ServletContainerInitializer 2020-06-15 19:39:35,736 INFO [main] [org.jboss.weld.bootstrap.WeldStartup] (WeldStartup.java:149) - WELD-000900: 3.1.2 (Final) 2020-06-15 19:39:36,107 INFO [main] [jboss.weld.environment.deployment.discovery.ReflectionDiscoveryStrategy] (ReflectionDiscoveryStrategy.java:49) - WELD-ENV-000014: Falling back to Java Reflection for bean-discovery-mode="annotated" discovery.
