Well they have you covered: > To balance the need for integrity with both the circumstantial, convenience uses of JDK internals and the essential uses, Java gives the user – the application's owner (typically its author, maintainer, or deployer) – the final say on which strong encapsulation boundaries are in place and which should be ignored. This freedom is offered under the guiding principle that the ability of one component to encroach on the boundaries of another must be explicitly granted by the application. Libraries cannot choose to obtain encapsulation-busting "superpowers" without the knowledge and consent of the application's owner.
