Gary Gregory commented on LOG4J2-1958:
--------------------------------------

Should we log a status logger warning if a {{SerializedLayout}} is used?

> Due to inherent security weakness of Java object serialization, see CVE-2017-5645, we should deprecate SerializedLayout and discourage its use. We should also remove it as default from the appenders which currently has it:
> * SocketAppender
> * JmsAppender
> For the time being, we can recommend using JsonLayout as a replacement.
