[jboss-jira] [JBoss JIRA] Commented: (JBLOGGING-20) JDK loggign isLoggable(Level.FINEST) returns false with Log4J backend

Ondrej Medek commented on JBLOGGING-20:
---------------------------------------

Well, I do not know exactly, where is the problem, but I think I have found two bugs.

The LOG is org.jboss.logmanager.LoggerInstance and this class is subclass of java.util.logging.Logger. The LoggerInstance class overrides the isLoggable(Level) method from the Logger class. This overridden method LoggerInstance.isLoggable(Level) uses a new value called effectiveLevel, which is:

effectiveLevel = 800, i.e. default value I guess, when I have configured to log ALL stuff for my category in log4j config file. It should be INT.MIN_VALUE (= Level.ALL.intValue()) instead.
effectiveLevel = 400, when I have configured to log TRACE stuff for my category in log4j config file. I.e. is is the same value, as Level.FINE.

Bug 1) Setting ALL level for the category in config file should set the effectiveLevel to Level.ALL.intValue().

Bug 2) Setting TRACE level for the category in config file makes the LOG.isLoggable(FINEST) always false, but LOG.finest("...") does make a log.

IMHO this "LoggerInstance.effectiveLevel" stuff is half baken: it is used only in isLoggable(), but is not used in the log() methods (doLog, fine, finer, finest, ...). Maybe it should be removed and the original Logger.levelValue should be used instead?  Then LoggerInstance would not need to override isLoggable().

> I have code using JDK logging like:

> I have no log. When I use just
> LOG.finest("added into list: " + something);
> I got a log in the log file.
> I use JBoss with Log4J. It is configured to log ALL stuff.
