There is no warning when replacing enum constructor with factory.

Steps to reproduce:

1) have a code:
public enum Enum {

    A(1);

    private Enum(int x) {
    }
}

2) replace constructor with factory

-> public enum Enum {

    A(1);

    private static Enum create(int x) {
        return new Enum(x);  // <--- here is error : Enum types cannot be instantiated 
    }

    private Enum(int x) {
    }
}
