子类completableFuture和CompletableFuture.All最终都无法正常工作

Question

我正在尝试创建CompletableFuture的子类，所有其他方面都运行良好，但是当我使用CompletableFuture.allOf时，它永远不会完成。

“ test2全部处理完毕”从未打印过-如果我将所有TimedCF替换为通用CompletableFuture，它将按预期工作。...

感谢您的帮助！

代码示例：

class TimedCF<T> extends CompletableFuture<T> {
CompletableFuture<T> orig = null;
    public TimedCF(CompletableFuture<T> ct) {
        this.orig = ct;
    }
 ... all other public methods delegated by intellij auto gen
 ... all static methods proxy to CompletableFuture
}

        TimedCF<String> cf1 = new TimedCF(CompletableFuture.completedFuture("string 1"));
        TimedCF<String> cf2 = new TimedCF(CompletableFuture.completedFuture("string 2"));

        CompletableFuture.anyOf(cf1, cf2)
                .handle( (ignore, ex) -> {
                    System.out.println("test2 all of handled");
                    return null;
                } );
