Invoking the {@link java.util.concurrent.CompletableFuture#cancel cancel} 51 * method on a {@code CompletableFuture} returned by this API will not interrupt 52 * the underlying operation, but may be useful to complete, exceptionally, 53 * dependent stages that have not already completed. 54 * 55 * <p> Unless otherwise stated, {@code null} parameter values will cause methods 56 * of all classes in this package to throw {@code NullPointerException}. 57 * 58 * @since 9 59 */ 60 package jdk.incubator.http;
