It is certainly related, although in practice I don't know how. In theory every minor version bump of `org.apache.logging.log4j` or `o.a.l.l.spi` can cause an incompatibility between API and implementation. In practice the implementations also rely on the API for `o.a.l.l.util` classes, so they will not work with a version that is too old. I would certainly bring some order here, if you have any ideas how... Piotr
