I see comments about how implementation details of the JRE (such as "com.sun" packages) must be hidden, but without reference to the threats that cause a problem.

It’s primarily a maintenance issue, IMO. It is common that we provide classes and methods that are intended to be used from elsewhere inside a product, but which we do not want users to see. That is, it is much the same as the reason you use “private” for class internals - if everything is publicly accessible, people use it, and you cannot refactor your code without breaking theirs.
