I don’t run the build with Java 11, although I do have projects that use it that are on Java 11. It seems that log4j-api is failing when compiling with Java 11 because sun.reflect.Reflection was removed in Java 9. I guess we need to modify the toolchains configuration to tell the main modules to use only Java 8 to compile. The only other option would be to create a jar that has that class in it and specify it as a provided dependency.
