MDC in Thread

[artsoftprivate]

Hi folks! I need help...

I have written a web service with Quarkus and log everything nicely in the log file. So far so good :-)

From my web service, I call another web service asynchronously in a new thread. There is no need to wait for the thread to finish.

Within this thread, there is only a need to monitor a few data and log them into the log file. When I build and test locally (so I'm in Quarkus DEV mode, IDE is IntelliJ), I see in the thread my MDC data (self-filled) in the log console. So far, so good as well :-)

However, when I build a native image from my code and launch it in Docker, all log entries written by the thread are completely filled with an empty MDC: "mdc":{ } ..... I have also already banished the "Map<String, String>" of the main MDC into a ThreadLocal instance and access it in the thread in order to explicitly reset and renew the MDC in the thread again. But the same effect: In every log entry written in the thread, the MDC always remains empty! And nobody knows why...

I'm going crazy!!!! Maybe you can help here?

Best regards
