Major Description
The latest 3.1.1-SNAPSHOT version fails with Java 12 with
javadoc: error - The code being documented uses packages in the unnamed module, but the packages defined in https://docs.oracle.com/en/java/javase/12/docs/api/ are in named modules.
Even if the fix from https://bugs.openjdk.java.net/browse/JDK-8212233 (explicitly setting source to 8) is applied.
