           Summary: java.lang.NoSuchMethodError:
                    org.apache.log4j.Logger.isTraceEnabled()Z
           Product: SLF4J
           Version: 1.5.x
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: blocker
          Priority: P1
         Component: Implementations
        AssignedTo: dev at slf4j.org
        ReportedBy: davidr at goodserver.com
        Depends on: 68


Same as bug 68, but in jcl-over-slf4j-1.5.2.jar. The SLF4J facade breaks when
the underlying logger is log4j-1.2.12 or earlyer, because it doesn't have the
trace methods. The logging calls completely shut down the current thread,
instead of silently doing nothing, or instead of logging as debug instead of
trace.
