can not catching unwrapCfException

[huhaosumail]

目前Cffu提供的catching方法可以比CompletableFuture的exceptionally方法更细化的针对准确类型的非包装类的异常进行细节处理。但是入参必须是已经从CompletableFuture转为Cffu的实例。

Cffu failed = cffuFactory.failedFuture(new IndexOutOfBoundsException());
System.out.println(CompletableFutureUtils.catching(failed,RuntimeException.class, ex -> 2).get());
System.out.println(CompletableFutureUtils.catching(failed,IndexOutOfBoundsException.class, ex -> 3).get());

但是入参如果是一个未被转化的CompletableFuture异常，该异常会被包装，在此情形下能否兼容处理呢？

CompletableFuture failed = CompletableFuture.supplyAsync(()->{
    throw new IndexOutOfBoundsException();
});
System.out.println(CompletableFutureUtils.catching(failed,RuntimeException.class, ex -> 2).get());
System.out.println(CompletableFutureUtils.catching(failed,IndexOutOfBoundsException.class, ex -> 3).get());

可以参考Guava的catching能够准确处理

ListeningExecutorService executorService = MoreExecutors.listeningDecorator(Executors.newFixedThreadPool(10));
ListenableFuture listenableFuture = executorService.submit(()->{
  throw   new UnsupportedOperationException("s");
});
System.out.println(Futures.catching(listenableFuture,RuntimeException.class, ex -> 2).get());
System.out.println(Futures.catching(listenableFuture,IndexOutOfBoundsException.class, ex -> 3).get());
