Async File Appender stopped working since 1.3.0-alpha13

Since 1.3.0-alpha13, my AsyncAppender referencing a FileAppender stopped working. It works in 1.3.0-alpha12 and before. Using the FileAppender directly still works, so the issue is the AsyncAppender. The problem is that it does not write anything to the file when it should have written 23 lines to the log file. My configuration is straight forward: https://github.com/Ahli/Galaxy-Observer-UI/blob/ba81d7ac331a258da2ddcce446ef d4d8c2d1e0ba/tools/observerUiSettingsEditor/project/src/main/resources/logba ck.xml I use it in combination with slf4j 2.0.0-alpha6 in a JDK 17 project that does not use any frameworks. I have tried the current snapshot of alpha14, but my issue is still present. Are there migrations necessary that were not announced in the news post or is this a bug?

dynamically change logging thesholds
by Norbert Kiesel 09 Feb '22

Hi, we often need to change log level thresholds to investigate a problem in a running system. Right now, we do that by using <configuration scan="true" scanPeriod="30 seconds"> and then editing the logback.xml file by hand (i.e. using a text editor or Sed or Perl). I wonder if there is a better way to accomplish this. I know that we can e.g. use <root level="${rootLevel}"/> but what I do not yet understand is: 1. Can I modify the value if this variable via some Java API from within my application? 2. Do we still need the scan="true" attribute or will the "rootLevel" variable be evaluated every time the logger is used? 3. Is there a measurable performance impact by using variables in that manner? </nk> --- [MetricStream]<http://www.metricstream.com/> Norbert Kiesel | Chief Architect [https://assets.metricstream.com/lp/email-signature-mail-icon-grey.png] nkiesel(a)metricstream.com<mailto:nkiesel@metricstream.com> [https://assets.metricstream.com/lp/email-signature-mobile-icon-grey.png] +1-650-620-2955 [https://assets.metricstream.com/lp/email-signature-phone-icon-grey.png] +1-650-620-2955 www.metricstream.com<https://www.metricstream.com/> [Linkedin]<https://www.linkedin.com/company/metricstream> [Facebook] <https://twitter.com/metricstream> [Twitter] <https://www.facebook.com/MetricStream> [youtube] <https://www.youtube.com/user/MetricStream> [https://assets.metricstream.com/lp/meticstream-email-signature-stream-bg.png]
