Volkan Yazici commented on LOG4J2-3104:
---------------------------------------

Thanks for the report [~avinash.tripathy]! Would you mind sharing your Log4j configuration, please? And I am a bit confused by your _"additionalData attribute is getting modified with complete json instead of empty"_ statement. Could you elaborate a bit on that?
