To replace the "brittle, error-prone, class-path mechanism" with a means for program components to declare dependencies on each other. Strong encapsulation, which allows a component to declare which public types are accessible to other components, is also a goal.

These features will benefit application developers, library developers, and implementers of the Java SE Platform itself directly, And indirectly, since they will enable a scalable platform, greater platform integrity, and improved performance. said Reinhold.
