异常：Could not register input pipe (already registered)

同一个pipe不能被注册多次
例如，
先使用PipeAdvertisement构造了一个JxtaServerSocket对象，
然后使用同一个PipeAdvertisement构造JxtaServerPipe对象，这是系统会抛出异常

java.io.IOException: Could not register input pipe (already registered) for urn:jxta:uuid-83A8BEEE6E0B421EB4059B445A02C0DA0B75BABF7FB9438EA2A7C0B9451056D304
