Raw types were common before generics were introduced in Java 5. Today, developers typically use raw types for compatibility with legacy code or interoperability with non-generic APIs.

Universal generics would allow Java type variables to range over primitive and reference types, making it easier to extend or reuse code across different types.

The project's goals include a major overhaul of Java's generics, a new approach to generic typing, and new support for value types.
