maven-javadoc-plugin is not skipped in Java 11 #844
Description
The version of Java 11 we use seems to ignore the presence of -Dmaven.javadoc.skip=true. It seems to be a popular bug.
There's a serious problem in the ecosystem with javadoc + maven + jdk 11
I tried looking around to add more flags to skip it but none of them work. My suggestion is that if we fallback to JDK 11, let's fallback to the highest patch release for it which is 11.0.28. I confirmed that replacing the JDK URL works for this case.
