Trying to configure e.g. a console-appender with a logging filter as described in
Wildfly 10 Logging Configuration

The server will startup and happily parse the configuration, but then exit without any error:
{{2017-06-22 15:12:28,185 DEBG fd 7 closed, stopped monitoring <POutputDispatcher at 140706226583888 for <Subprocess at 140706228894320 with name wildfly in state RUNNING> (stdout)>

The culprit is the order of the levels in the range expression, which is the wrong way around.
The correct order (which makes more sense anyway) is e.g. [DEBUG,WARN) not [WARN,DEBUG)
