Major Description
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.
