Subject [jira] [Commented] (LOG4J2-1353) Logger 'Object... params' arguments should always be appended even if {} is missing
Date Tue, 05 Apr 2016 14:53:25 GMT

    [ https://issues.apache.org/jira/browse/LOG4J2-1353?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15226400#comment-15226400

Gary Gregory commented on LOG4J2-1353:
--------------------------------------

I do not think we should do anything if a solution slows down processing or creates more Objects.
This is a programming error.

> 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.
