If you want to guarantee that all classes in a package come from the same code source, use JAR sealing. A sealed JAR specifies that all packages defined by that JAR are sealed unless overridden on a per-package
Ifcom.sun.java.jagis the fully qualified name of a type, then there cannot be any package whose fully qualified name is eithercom.sun.java.jagorcom.sun.java.jag.scrabble. The hierarchical naming structure for packages is intended to be convenient for organizing related packages in a conventiona...
Good things come in small packages.—Traditional proverb Java programs are organized as sets of packages. Each package has its own set of names for types, which helps to prevent name conflicts. A type is accessible (§6.6) outside the package that declares it only if the type is declared ...

Once programs start to get larger and larger, Java packages become more and more important to use for organization. They help to group like components of the program together.
For extensibility and usability, a mechanism is required to coordinate the activity of multiple editor programs (each specializing in particular source types) with the JP versioning system. The JP architecture makes it possible, using a very simple framework, to coordinate loosely coupled Java-...
Our solution is very efficient to compute and is based on a newly introduced, seemingly unrelated security feature of Java file archives. On average, our analysis "seals" (safely devirtualizes) about 39% of the virtual calls (to non-final methods) that appear in SPECjvm98 programs, and ...

In general, writing java programs that rely on sun.* is risky: those classes are not portable, and are not supported.
