/**
 * <h2>High level HTTP and WebSocket API</h2>
 *
 * <p> Provides high-level client interfaces to HTTP (versions 1.1 and 2) and
 * WebSocket. The main types defined are:
 *
 * <ul>
 *    <li>{@link java.net.http.HttpClient}</li>
 *    <li>{@link java.net.http.HttpRequest}</li>
 *    <li>{@link java.net.http.HttpResponse}</li>
 *    <li>{@link java.net.http.WebSocket}</li>
 * </ul>
 *
 * <p> Asynchronous tasks and dependent actions of returned {@link
 * java.util.concurrent.CompletableFuture} instances are executed on the threads
 * supplied by the client's {@link java.util.concurrent.Executor}, where
 * practical.
 *
 * <p> {@code CompletableFuture}s returned by this API will throw {@link
 * java.lang.UnsupportedOperationException} for their {@link
 * java.util.concurrent.CompletableFuture#obtrudeValue(Object) obtrudeValue}
 * and {@link java.util.concurrent.CompletableFuture#obtrudeException(Throwable)
 * obtrudeException} methods. Invoking the {@link
 * java.util.concurrent.CompletableFuture#cancel cancel} method on a {@code
 * CompletableFuture} returned by this API will not interrupt the underlying
 * operation, but may be useful to complete, exceptionally, dependent stages
 * that have not already completed.
 *
 * <p> Unless otherwise stated, {@code null} parameter values will cause methods
 * of all classes in this package to throw {@code NullPointerException}.
 *
 * @since 11
