People may not install zookeeper locally, we need to restore the behavior to use multicast as default registry.

Hi, have you installed zookeeper and started it locally before running this demo? If so, it will work. But not everyone will install the zookeeper locally. Normally we want to provider a convient way for user to try out the demo easily. So we use multicast as the default.

@ralf0131 are you referring to incubator-dubbo/dubbo-demo/dubbo-demo-provider's Provider example? I just run it and it seems to be working fine ? If this is project you are referring then would you see I am missing something here?

Hi, I've checked out the latest code, the issue has been fixed. The default registry has been changed back to `multicast`. I am going to close this issue.
