Description

description: when we use the method updatetLoggers() in LoggerContext, the old configuration is the same with the new configuration(i.e. The expression 'old == config' is always true), why do we need to update the configuration and fire a property change event?

The code below is from LoggerContext, for your information.

    public void updateLoggers() {
        updateLoggers(this.configuration);
    }

    public void updateLoggers(final Configuration config) {
        final Configuration old = this.configuration;
        for (final Logger logger : loggerRegistry.getLoggers()) {
            logger.updateConfiguration(config);
        }
        firePropertyChangeEvent(new PropertyChangeEvent(this, PROPERTY_CONFIG, old, config));
    }
