              I just copied and pasted the snippet shown in this page.
              So there was nothing strange, I think.

              <?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
  <Appenders>
    <Console name="STDOUT" target="SYSTEM_OUT">
      <ThresholdFilter level="INFO" onMatch="ACCEPT" onMismatch="DENY"/>
    </Console>
          :

              Please refer to my comment on another ticket as well. The symptom
              I guess the both issues seem to come from the same cause.

              Log4jLogEvent constructor and RingBufferLogEvent.getLevel now convert null Level to Level.OFF to prevent NPEs.

              Fixed in revision 1555339.
              Please verify and close.
