Summary

Add a new enum constant RELEASE_16 to javax.lang.model.SourceVersion for the JDK 16 release and update the FooVisitor14 visitors to cover release 16 as well.

Problem

The SourceVersion enum needs an enum constant for each release being modeled.

Solution

Append the enum constant RELEASE_16 and update the visitor text and supported source version annotations to cover from RELEASE_14 to RELEASE_16.
