Sure, its only if you use MDC, and its not even Jigsaw that does it
(relates to version changes). See
https://github.com/elastic/elasticsearch/blob/f01f15d3b8592db4210f725f0c37baff4a554a35/core/src/main/java/org/apache/log4j/Java9Hack.java
if you want a hack.
Its just an example of how much software won't work with java 9 out of
box. Still looking forward to it!
Yeah, changing the version-string scheme, particularly dropping the
leading `1.` has impacted a lot of libraries. Every effort was made to
communicate that change and has all the others with significant
compatibility impact. I would hope that most libraries that need update
will be updated by the time that JDK 9 ships. Good point on unmaintained
libraries.
