ContextBase[FromLogback1.2.3],The reset method should not call propertyMap.clear(); otherwise the properties of the application configuration no longer exist when the logback.xml change and reload by the monitor, such as ReconfigureOnChangeTask#performXMLConfiguration

   public void reset() {

        removeShutdownHook();
        getLifeCycleManager().reset();
        propertyMap.clear();
        objectMap.clear();
    }

should be changed to

   public void reset() {
        removeShutdownHook();
        getLifeCycleManager().reset();
        objectMap.clear();
    }
