Ralph Goers commented on LOG4J2-2038:
-------------------------------------
This problem is caused because Dex is inspecting class files in the
META-INF/versions directory. A bug should really be reported against that tool
as it has no business looking at class files under the META-INF directory.
That said, we have been looking at alternate approaches to deal with this as
noted in LOG4J2-1921. But we won't be dropping support for Java 9 to fix this.
