Subject [jira] [Created] (LOG4J2-1353) Logger 'Object... params' arguments should always be appended even if {} is missing
Date Tue, 05 Apr 2016 07:19:25 GMT
Alex Berg created LOG4J2-1353:

             Summary: Logger 'Object... params' arguments should always be appended even if
{} is missing
                 Key: LOG4J2-1353
                 URL: https://issues.apache.org/jira/browse/LOG4J2-1353
             Project: Log4j 2
          Issue Type: New Feature
          Components: API
    Affects Versions: 2.5
            Reporter: Alex Berg
            Priority: Minor

The Logger.warn/info/trace etc. has methods that take ... object list. It maps into message
where {} is given. If there are fewer {} than arguments in list, it ignores argument. Who
would ever desire to have an argument ignored? That is to me clearly a bug in the design,
but of cause I may be missing something.

I suggest to always append the unmatched extra arguments and separate them by a space or a
comma. I'm not sure if the last argument is logged as an exception if it is an exception,
in that case the solution should gracefully handle that.

A super nice feature would be if it was possible to configure the append of the unmatched
arguments, but I think that is more work than it is worth.
