For some reason you are using j.u.l instead of log4j or slf4j. And you want to se your logs of level LOWER than
WARNING. You’ve done even
logger.setLevel(Level.ALL); and yet nothing below
WARNING is ever printed out. You’ve checked the logging method and they are the same. WTH?!!
Well, set console handler log level, cause in j.u.l log level is the minimum of logger and handler level. To do that, put in your properties file:
java.util.logging.ConsoleHandler.level = FINEST
Or, if – like me – you wish the console handler would just follow logger level, set it to
ALL in global (JDK) settings:
sudo vim /usr/lib/jvm/default-java/jre/lib/logging.properties
The file is write-protected, so sudo.
