Subject Re: what version are RollingFileAppender.newBuilder() and RollingFileAppender.Builder.setConfiguration supported in?
Date Tue, 16 Jan 2018 20:16:31 GMT
In general, you should be using the current version 2.10.0. Any reason you
are digging deep into old versions?

Also, I've not been very strict about using @since in log4j-core. In
log4j-api, we are very careful to do it all "right.""
