That's the point for using ports in the first place, no?
^ Hmmm? The servers in the test use a random port that's available. The clients connect to these ports. The local ports used by the clients are random. You need to use APIs such as [2] to fix them. So, what exactly are you talking about? Are you saying we should fix the local client ports? As I said in the first post, we could try to find a random port that's not the server one... I must admit this scenario sounds very weird... how does Java allow you for a local port to be bound to a port that's already in use by the server? It doesn't make sense. I'll be trying to replicate this in a small unit test next few days...
