           Summary: jcl104-over-slf4j not recompiled with modified
                    LocationAwareLogger
           Product: SLF4J
           Version: 1.4.x
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: blocker
          Priority: P1
         Component: Implementations
        AssignedTo: dev at slf4j.org
        ReportedBy: Filip.Jirsak at gmail.com


Log level contstants was modified in LocationAwareLogger.java (see bug #23).
But jcl104-over-slf4j was not recompiled after that change. Because java
compiler sometime puts constants into target method, there are sometime old
values of these constants in jcl104-over-slf4j classes in
http://www.slf4j.org/dist/slf4j-1.4.3.zip

For example, in class org.apache.commons.logging.impl.SLF4JLocationAwareLog
there is following method:

  public void warn(Object message) {
    logger.log(null, FQCN, LocationAwareLogger.WARN_INT,
String.valueOf(message), null);
  }

In current class it is compiled as:

  public void warn(Object message) {
    logger.log(null, FQCN, 2, String.valueOf(message), null);
  }


because 2 was old value of LocationAwareLogger.WARN_INT. It results in
following exception:

java.lang.IllegalArgumentException: 2 not a valid level value
        at ch.qos.logback.classic.Logger.log(Logger.java:820)
        at
org.apache.commons.logging.impl.SLF4JLocationAwareLog.warn(SLF4JLocat
ionAwareLog.java:141)

Perhaps all classes of sl4j needs recompilation.
