Answer
Annotations are available to the JVM but not at runtime.
RetentionPolicy.CLASS retains annotations in the bytecode but discards them at runtime. This is useful for tools that operate on class files without needing runtime access, such as certain debuggers or bytecode analyzers. However, it's not suitable for frameworks requiring runtime reflection, as the annotations won't be available when the program runs.
