Bug in switch around Enums?

[Ted Neward]

A good friend of mine just stumped me with this one; forwarding here because
I believe it to be a bug in the compiler somewhere. Couldn’t remember if
Josh and Neal were on the list, so I added them in CC; sorry for the
duplication, guys.

 

Normally, case statements with or without parens around them will compile:

 

                int x = 0;

                switch (x) {

                        case (0): return "ZERO";

                        case 1 : return "ONE";

                }

 

But doing the same for Enum doesn’t compile when parens are there:

 

public class EnumTest

{

  public enum Test { WRAP, STAGGER, ROTATE, NONE };

  public static String toString(Test e) {

    switch (e) {

      //case (EnumTest.Test.STAGGER): return “STAGGER”;   // this will not
compile 

      case WRAP: return "WRAP";   // This, of course, is fine

      default: return "WTF?!?";

    }

  }

}

 

Is this a compiler/parser bug?
