Mismatched unsafe access to non escaping object fails

public class MismatchedUnsafeLoadFromNewObject {
    public volatile int f_int = -1;

    public static Unsafe unsafe = Unsafe.getUnsafe();
    public static final long f_int_off;

    static {
        Field f_int_field = null;
        try {
            f_int_field = CASandCAEwithNegExpected.class.getField("f_int");
        } catch (Exception e) {
            System.out.println("reflection failed " + e);
            e.printStackTrace();
        }
        f_int_off = unsafe.objectFieldOffset(f_int_field);
    }

    static public void main(String[] args) {
        for (int i = 0; i < 20_000; i++) {
            byte res = test1();
            if (res != -1) {
                throw new RuntimeException("Incorrect result: " + res);
            }
            res = test2();
            if (res != -1) {
                throw new RuntimeException("Incorrect result: " + res);
            }
        }
    }

    static byte test1() {
        MismatchedUnsafeLoadFromNewObject t = new MismatchedUnsafeLoadFromNewObject();
        return unsafe.getByte(t, f_int_off);
    }

    static byte test2() {
        MismatchedUnsafeLoadFromNewObject t = new MismatchedUnsafeLoadFromNewObject();
        return unsafe.getByte(t, f_int_off+1);
    }
}

test1() causes the compiler to crash, test2() returns incorrect result
