Why are TRACE level messages logged if the root logger level set to log lower than quarkus.log.min-level?

Solution In Progress - Updated -


If a lower log level than quarkus.log.min-level is set to the root logger, messages are logged even though the log level is lower than quarkus.log.min-level.

For example, if TRACE is set to quarkus.log.level and then calling org.jboss.logging.Logger#trace(Object message) method in an application class, implicit quarkus.log.min-level default value DEBUG is not applied to the root logger. As a result, the TRACE level log which is a lower log level than quarkus.log.min-level, will be logged to the console.


# the default value of min-level is DEBUG
# quarkus.log.min-level=DEBUG

public class GreetingResource {

    Logger log;

    public String hello() {
        log.trace("Hello RESTEasy");
        return "Hello RESTEasy";
