javac is generating an incorrect LVT table for code like:

public class Test {
    public Object m(int i) {
        Object c;
        switch (i) {
            case 0:
                Object o = null;
                if (o != null) {
                    return o;
                }
            case 1:
                Object s = null;
                c = null;
                break;
            default:
                throw new AssertionError("");
            }
        return c;
    }
}
