LevelMatchFilter not working as expected

           Summary: LevelMatchFilter not working as expected
           Product: Log4j
           Version: 1.2
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Other
        AssignedTo: log4j-dev@jakarta.apache.org

LevelMatchFilter works as documented but not as expected.  The logic used by 
the decide(LogginEvent) method differs from what is expected by user and from 
looking at the logic employed by the filter LevelRangeFilter.

LevelRangeFilter's logic, and what I would expect LevelMatchFilter to use, is 
to return a Filter.DENY when the levels don't match,  Filter.ACCEPT if they 
match and property acceptOnMatch is true and Filter.NEUTRAL if acceptOnMatch 
is false to allow other filters to process a "valid" level event for this 
appender.

Right now, I'm using an appender for which I would like to only process events 
that are of level INFO.  So I assume a LevelMatchFilter would do the job since 
it attempt to do an exact match of levels.  Unfortunately, the appender is 
recording ALL levels.  

The only way you can get it working as expected is to do what is stated in the 
comment for bug #6773 http://nagoya.apache.org/bugzilla/show_bug.cgi?id=6773 
which is to add a second filter DenyAllFilter.
