>Description:
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;
	}
    }
}
