I think this is a better approach than the current code that uses a Thread. Therefore, I think we can close #544. I have been reviewing the PR and overall I like it. I have noticed that it is possible to lose log messages during shutdown (add a 100ms delay just before the call to publish internal to simulate a large backlog). The threading approach originally suffered from this problem as well and I think the same solution will work (register uses of the AsyncHandler and explicitly shutdown the executor during JULI shutdown). I plan on working on this today. |

This provides an alternative solution to the
LoggerThreadproblems described in #544.It replaces
LoggerThreadwith a single-threadedExecutorServicealmost identical to the one used byFileHandler. This improvesAsyncFileHandlerin two aspects:Errorkills the working thread, it is regenerated by the executor service.A test is provided to ensure that the previous overflow policies work as documented.
