     * Since Java 9, reflection is severely restrained, and a new API {@link MethodHandles.Lookup#defineClass} is introduced.
     * However, this API can only "defines a class to the same class loader and in the same runtime package and protection domain as this lookup's lookup class",
     * which means, we can only use this API safely in the decorating scenario where the decorated class acts as the lookup object.

*A noticeable trait of this expansion is that it chooses unique hosts such the setup provides maximum protection and availability.*

- Choosing an erasure set for the object is decided during `PutObject()`, object names are used to find the right erasure set using the following pseudo code.
