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

             Summary: Logger cache does not account for message factory
                 Key: LOG4J2-1180
                 URL: https://issues.apache.org/jira/browse/LOG4J2-1180
             Project: Log4j 2
          Issue Type: Bug
          Components: API
    Affects Versions: 2.4.1
            Reporter: Gary Gregory


The Logger cache does not account for a logger's message factory.

If you call {{LogManager.getLogger(Class|Object|String, MessageFactory)}} and then call a getLogger() API again with the same {{Class|Object|String}} a different message factory, you get the Logger that was first created which means you will not get the proper formatted messages.

For example:

{code:java}
Logger loggerA1 = LogManager.getLogger("A", messageFactory1);
Logger loggerA2 = LogManager.getLogger("A", messageFactory2);
{code}

loggerA1 is the same as loggerA2.

This is a problem if two unrelated code bases (jars) both the same Logger names|objects|classes.
