HHH-11838 Closed introduced a potential bug that occurs whenever the persistent field has both a corresponding is and corresponding get method. E.g., given:

@Entity
class MyEntity
    @Id
    Integer id;
    @Basic
    String someValue;

    ...

    String getSomeValue() {
        ...
    }

    boolean isSomeValue() {
        ...
    }
}

The fix for HHH-11838 Closed attempted to reuse the code that is used to resolve the getter method for property-access, in which case it is illegal for there to be both. That is not the case here however.
