* Missing null checks may cause NullPointerException
* Bridging with Kotlin code is polluted with platform types
* Some public APIs have incorrect nullability annotations (both overly restrictive and overly permissive)

While there are competing ways to represent absence (`Optional`, "Null Object" pattern, method overloads),
it is unlikely that we'll be able to remove `null` entirely.

The default parameters used by the `CORSMiddleware` implementation are restrictive by default, so you'll need to explicitly enable particular origins, methods, or headers, in order for browsers to be permitted to use them in a Cross-Domain context.

The following arguments are supported:

     * <p>
     * This method allows you to specify a custom ObjectInputFilter for fine-grained
     * control over which classes can be deserialized. Use this when the default filter
     * is too restrictive or permissive for your use case.
     * </p>
     *
     * @param bytes the byte array (must not be {@literal null})
     * @param filter the ObjectInputFilter to use, or null to disable filtering
