RE: Async logger not logging after upgrading tomcat, jdk and log4j

Hello,

I have checked the debug log using '-Dlog4j2.contextSelector' (that does not log) with the debug log without using this variable.

I can't see any differences, except obviously the messages regarding async contexts:

Hello,

Here is the trace when starting tomcat with '-Dlog4j2.contextSelector=org.apache.logging.log4j.core.async.AsyncLoggerContextSelector':
https://gist.github.com/joanbalaguero/1fa286417bfc9dbd3ce75e043bd26f3d

It seems the async contexts are started, but maybe someone can see something wrong that makes the log does not work.

Thanks,

Joan.
