JDK-8227634 optimized object array accesses when casting an element loaded from an array to a known type or storing an object of a known type to an array. This optimization should be extended to also work when the type is only known after parsing. For example:

    Integer test90_value = new Integer(rI);

    @ForceInline
    public Object test90_value() {
        return test90_value;
    }

    // Same as test81 but with type only known after inlining
    @Test(failOn = ALLOC_G + ALLOCA_G + LOAD_UNKNOWN_VALUE + STORE_UNKNOWN_VALUE + VALUE_ARRAY_NULL_GUARD)
    public Object test90(Object[] array, Object o, int i) {
        Object v = test90_value();
        if (v == null) {
          return null;
        }
        array[0] = v;
        array[1] = array[0];
        array[2] = o;
        return array[i];
    }

    @DontCompile
    public void test90_verifier(boolean warmup) {
        Integer i = new Integer(rI);
        Integer[] array1 = new Integer[3];
        Object[] array2 = new Object[3];
        Object result = test90(array1, i, 0);
        Asserts.assertEquals(array1[0], i);
        Asserts.assertEquals(array1[1], i);
        Asserts.assertEquals(array1[2], i);
        Asserts.assertEquals(result, i);
        result = test90(array2, i, 1);
        Asserts.assertEquals(array2[0], i);
        Asserts.assertEquals(array2[1], i);
        Asserts.assertEquals(array2[2], i);
        Asserts.assertEquals(result, i);
    }
