[networking] Possible fixes for Jme3test examples

While trying to work with:




I could not get them to run. Latency would simply give me some kind of buffer overflow error and Messages would give me the Sending Ping Message! output but would never receive the message.

I then noticed that in TestHostDiscovery.java that


was called, assumably to allow the client time to connect.

So, when I applied


to both tests before the client attempted to do anything, they worked!

I dont know if anyone else was having similar problems. I just wanted to let you guys know.

These tests worked when I wrote them, but since then many changes happened to the network system.
