> In GroomServer, we call BSPNetUtils.getNextAvailable to assigning the bsppeer
> listening port. After figures out an available port, the GroomServer release
> the port and launches the BspPeer(Child), then the child listens to this port.
> However, during the GroomServer release the port and peer listens the port,
> if other process in the operation system binds to the same port occasionally,
> the bsppeer will fail to start up because of "Address already in use"
> exception.
