> Key: GROOVY-4612
> URL: https://issues.apache.org/jira/browse/GROOVY-4612

> Issue Type: Bug
> Components: Compiler
> Affects Versions: 1.7.5, 2.4.0-beta-3
> Environment: Windows 7
> Reporter: Ron Gross
> Priority: Major
>
> Declaring an enum and using it in a switch causes compilation errors:
> {code}
> class EnumTest {
> enum Operation {
> Insert,
> Delete,
> Find,
> }
> public static void main(String[] args) {
> foo();
> }
> public static void foo() {
> final Random rand = new Random();
> int opVal = rand.nextInt(Operation.values().length);
> Operation op = Operation.values()[opVal];
> switch (op) {
> case Insert:
> System.out.println("Inserting");
> break;
> case Delete:
> System.out.println("Deleting");
> break;
> case Find:
> System.out.println("Finding");
> break;
> default:
> throw new RuntimeException("Unrecognized operation: " + op);
> }
> }
> }
> {code}
> The error:
> {noformat}
