BTW, https://issues.apache.org/jira/browse/MNG-5227 was about making the optional flag of a dependency manageable.
Previously any optional flags in dependencyManagement sections were ignored, and it looks like the Log4j build relies on that historical behaviour. For example the jackson dependencies are all currently marked as optional in the top-level dependencyManagement. With previous versions of Maven these managed flags were simply ignored and had no effect on the build. With the 644ac9c40ad41bf61e3b099918af33b8eb950621 maven build these optional flags were now being managed across any jackson dependencies in all sub-projects. Since jackson-module-jaxb-annotations was not declared as a direct dependency in log4j-core, but was only a transitive dependency of jackson-dataformat-xml, this ended up being marked as ‘optional’ and removed from the test-classpath. Removing the ‘optional’ flags from the dependencyManagement section in the top-level pom.xml cleans up the build and should work with both old and future versions of Maven.
