> Reporter: Stefanos Chaliasos

> I have the following Groovy program.
> {code:groovy}

> public class Main {
> static byte x = 1;
> public static byte foo() {
> 1
> }
> public static void main(String[] args) {
> x = (true) ? 0 : foo() // this does not work
> // the following works
> if (true) {
> x = 0
> } else {
> x = foo()
> }
> byte y = (true) ? 0 : foo() // this doesn't work as well
> }
> }
> {code}
