-----------------------------------

             Summary: Concrete Filter implementations should override equals and hashCode
                 Key: LOG4J2-1593
                 URL: https://issues.apache.org/jira/browse/LOG4J2-1593
             Project: Log4j 2
          Issue Type: Improvement
          Components: Filters
            Reporter: Remko Popma


For {{CompositeFilter.remove(Filter)}} to work correctly, concrete Filter implementations should override {{equals}} and {{hashCode}}. 

This is because CompositeFilter uses List.remove(Object), comparing by equality. Applications that keep a reference to the Filter object that was registered will work, but for example registering and unregistering serialized and deserialized instances via JMX will not work without this.
