Cant get switch statements working with enumerator. [message #200074]

Hi Guys...I've just downloaded 3.1 M6, and hoped the switch statement with
enums was working. It seems, if I trawl through the bug lists, people are
able to perform switch statements on enums. So what am I doing wrong?
Below, my code.

Cheers,
Martin

public class EnumTester {

public enum color {black, white}

public void test(color c) {
switch (c) {
case color.black:
System.out.println("Black");
break;
case color.white:
System.out.println("White");
break;
}
}
}

I forgot to mention, my workspace is set the compile with jdk 5.0, and the
exception I'm getting was:

The enum constant EnumTester.color.black reference cannot be qualified in
a case label

Cheers

Remove qualification as the compiler tells you. Simple names are required
there (as per JLS).
For some obscure reason, quite counter-intuitive, this unnecessary
constraint got added to Java 5. Blame the spec <g>

Thanx Philippe. Was just weird the way the code is formulated. Got it
working, thanx.

Feel free to suggest a better error message, that we control.

FYI: I filed enhancement request
https://bugs.eclipse.org/bugs/show_bug.cgi?id=90140
for a quick fix for this.
