In a very simple intro-style prototype using logback, I’ve got a rolling file appender logging correctly to a file.

However, I don’t see the log lines immediately; however, they do show up when I close my java app. This means things are getting buffered.

But I can’t find something like Logger.flush() or any flush method as a work my way back up the inheritance tree.

How do I ensure immediate flushing?

Thanks.
