Why shouldn't Java enum literals be able to have generic type parameters?

Question

Java enums are great. So are generics. Of course we all know the limitations of the latter because of type erasure. But there is one thing I don\'t understand, Why can\'t I

Answer 1

I think because basically Enums can't be instanced

Where would you set the T class, if JVM allowed you to do so?

Enumeration is data that is supposed to be always the same, or at least, that it won't change dinamically.

new MyEnum<>()?

Still the following approach may be useful

public enum MyEnum{

    LITERAL1("s"),
    LITERAL2("a"),
    LITERAL3(2);

    private Object o;

    private MyEnum(Object o) {
        this.o = o;
    }

    public Object getO() {
        return o;
    }

    public void setO(Object o) {
        this.o = o;
    }   
}
