According to the explanation persistent fields may be of any visibility because thay are accessed through getters/setters.
But why is the answer to the question:
"Persistent fields of an entity class must be public, private, protected, or package visibility."
still FALSE?
Maybe, I get it wrong, but the explanations says they mustn't...

As per section 2.2 of the JPA specification, "The instance variables of a class must be private, protected, or package visibility independent of whether field access or property access is used".
