      Description

        JDK 21 introduced pattern matching in the Java language. However, `javac` allowed `final` in front of a record pattern, such as (`case final R(...) ->`), something which is not allowed by the Java Language Specification.

        Programs that could be compiled erroneously in JDK21 with `final` will now fail to compile. This change fixes the issue in the compiler. Impacted users will need to remove the `final` keyword.
