The compiler allows this but probably shouldn't (javac rejects it).

public enum E {
  A;
  private void foo() {
    E e= new E() {
    };
  }
}

We should complain. Enums cannot be subclassed by user code (only enum constant
bodies can do so).

Thanks for finding it

The patch doesn't work.
The test needs to be:
receiverType.isEnum() && type != null
