The GCJ front-end should reject this, as the cases y.a and y.b don't match the definition of ConstantExpression in section 15.28 of the JLS (as required for cases in a switch in section 14.10 of the JLS):
public class test {
static final int a = 1;
static final int b = 2;
public static void main(String[] args) {
int x = 2;
test y = new test();
switch(x) {
case y.a:
System.out.println("Equal to a");
break;
case y.b:
System.out.println("Equal to b");
break;
default:
System.out.println("Something random");
break;
}
}
}
