Issues with log levels

[Andrus Adamchik]

I have bootique-logback and bootique-jetty modules in a simple app. The following two configurations (root logger "off", Jetty logger "off") should both result in suppressing Jetty logs completely. Yet they don't...

log:
  level: "off"

log:
  loggers:
    org.eclipse.jetty :
      level: "off"

INFO  [2022-01-31 13:31:05,014] main o.e.jetty.util.log: Logging initialized @678ms to org.eclipse.jetty.util.log.Slf4jLog

Only when I combine the two, I can silence the log:

log:
  level: "off"
  loggers:
    org.eclipse.jetty :
      level: "off"
