> Stateless ClassLoader isolation implementation (NIFI-9576) expects that the system class loader is an {{URLClassLoader}} instance but it is not true for Java 11. Due to this, {{BlockListClassLoader}} gets initialized with an empty set of classes and it cannot block anything (there is no isolation, otherwise it works on Java 11 as before NIFI-9576)
