I have not started work on this yet, but from looking at http://blog.joda.org/2017/04/java-9-modules-jpms-basics.html <http://blog.joda.org/2017/04/java-9-modules-jpms-basics.html> it seems we are going to have problems with a) plugins that are in different jars (modules) that use the same namespace and b) log4j-core as it currently exists.
Item b is a problem because the module-info for log4j-core should have a requires ONLY for log4j-api. For example, I’m not sure how we can have an optional dependency on Jackson. Item a is a problem if we create multiple jars (modules) for different network components but try to place them all under org.apache.logging.log4j.net <http://org.apache.logging.log4j.net/>. Thoughts? Ralph
