Remko Popma commented on LOG4J2-547:
------------------------------------
Interesting. This looks like a problem in the stack trace-walking logic to me:
it ignores the possibility that the FQCN appears multiple times and assumes the
first hit is the correct one. If the strack trace-walking logic were to read
_bottom-up_ it would correctly return
{{LoggerPrintStreamCallerInfoTest.print_chararray() line: 74}} as the location,
no?

> I've got some ideas on how to improve the LoggerStream idea that I added a
> little while ago. The main thing I'd like to do is extract an interface from
> it, rename the default implementation to SimpleLoggerStream (part of the
> SimpleLogger stuff), and allow log4j implementations to specify a different
> implementation if desired.
> In doing this, I'm not sure where specifically I'd prefer the getStream
> methods to be. Right now, it's in Logger, but really, it could be in
> LoggerContext instead. I don't think I should be required to get a Logger
> just to get a LoggerStream.
> Now if only the java.io package used interfaces instead of classes. This
> would be so much easier to design!
