That async appender looks quite interesting.  Does it provide any measurable benefit in normal logging?  Or do you only have because your stacktrace cleaner is heavy-weight? It does concern me that it uses an Executor with an unbounded queue which could not only cause out-of-memory exceptions, but also messages to not be saved on application shutdown (potentially).

But I do like the idea of it, as I log to log files over the network, not local disk and it's not always that fast.

There's an example logback.xml showing how to use them:
