Class ScopedValuesIncubatorNotes

java.lang.Object
net.jrodolfo.java_evolution.java20.ScopedValuesIncubatorNotes
public class ScopedValuesIncubatorNotes extends Object
Explains scoped values, introduced as an incubating API in Java 20.

ThreadLocal can pass contextual data through a call stack without adding parameters everywhere, but mutable thread-local state is easy to leak or forget to clean up. Scoped values were introduced to provide a safer model for sharing immutable context within a bounded execution scope.

The Java 20 API was incubating, so this repository documents the problem and intent without depending on the incubator module.
