In our nightly build, we run all modules against Java 11. [1] The only reason we do not compile with Java 11 is that we want to specifically test that our finally released jars that are compiled with Java 8 also work with Java 11. So there should be no reason to stick with Java 8; documentation is likely outdated.
The exception is that Hive and other Hadoop stuff does not support Java 11 in its entirety and we keep the Java 8 requirement to make it simple (= we don't need to explain what runs with Java 11 and what not).
