I've been trying to use the new feature of the MDC without any luck.. it's probably a silly question, but can someone please post exact format for it?

I've tried it without any luck...

from what I've seen in the examples it seems like 

%X{req.xForwardedFor:-NONE} 

 

should work.. but for me it keeps on saying:

ScanException: Expecting }

under Parser.expectCurlyRight

version is 1.0.12 with slf4j 1.7.5

Help is much appreciated ;)
