             Summary: Upgrade logback to 1.1.7
                 Key: QPID-7468
                 URL: https://issues.apache.org/jira/browse/QPID-7468
             Project: Qpid
          Issue Type: Improvement
          Components: Java Broker
    Affects Versions: qpid-java-6.0.4
            Reporter: Alberto


The current version used in qpid-broker 6.0.4 for logback is 1.1.3. With the version 1.1.7 logback broke backwards compatibility in  StatusManager interface (ch.qos.logback.core.status.StatusManager).

After this change, BrokerFileLoggerImpl is failing to add the `BrokerFileLoggerStatusListener` to the loggerContext due to binary incompatibility  (See line 210 of BrokerFileLoggerImpl for more info).

```java
 @Override
    protected Appender<ILoggingEvent> createAppenderInstance(Context loggerContext)
    {
        SystemConfig<?> systemConfig = (SystemConfig<?>)getParent(Broker.class).getParent(SystemConfig.class);
        _logbackStatusListener = new BrokerFileLoggerStatusListener(this, systemConfig);
        _statusManager = loggerContext.getStatusManager();
        _statusManager.add(_logbackStatusListener);

        final RollingFileAppender<ILoggingEvent> appender = new RollingFileAppender<>();
        AppenderUtils.configureRollingFileAppender(this, loggerContext, appender);
        return appender;
    }
```

We've noticed this after update spring boot to the latest version 1.4.1.Release which includes logback 1.1.7.

As a workaround, you can still downgrade your version of logback in your project to 1.1.3 but it would be nice to have it upgraded
