PipedInputStream pin = new PipedInputStream();                    PipedOutputStream pout = new PipedOutputStream(pin);                    new Thread(new Runnable() {                        public void run() {                            try {                                IOUtils.copy(ais, pout);                                pout.close();                            } catch (IOException e) {                                // TODO Auto-generated catch block                                e.printStackTrace();                            }                        }                    }).start();                    ArchiveInputStream inJar = new ArchiveStreamFactory()                            .createArchiveInputStream(ArchiveStreamFactory.JAR,                                    pin);

以上代码是没有问题，如果使用 pin 的代码和 pin 的声明代码中间隔了太多的代码就会产生此异常。具体没有做试验，也可能是有逻辑判断语句的原因。
