Class ScopedValuesPreviewNotes

java.lang.Object
net.jrodolfo.java_evolution.java21.ScopedValuesPreviewNotes
public class ScopedValuesPreviewNotes extends Object
Explains scoped values as a Java 21 preview feature.

Contextual data such as request IDs or security context is often passed with ThreadLocal, but thread-local state can be mutable and difficult to clean up correctly. Scoped values provide immutable context bound to a limited execution scope.

The Java 21 API was preview, so this repository keeps the feature as notes.
