According to the free www.examclouds.com (not the ePracticeLab, which is myexamclouds.com),
under ORM section, question 4:
Access for get and set method for property access in entity.
Protected or public or visibility.
I think it should be only protected or public.
According to the spec :
The instance variables of a class must be private, protected, or package visibility independent of
whether field access or property access is used. When property access is used, the property accessor
methods must be public or protected
