`Utils#startServiceOnPort` adjusts the range of port so I simply pass the
random value to the method. But I noticed we should pass the value > 0.
val tryPort = if (startPort == 0) {
startPort
} else {
// If the new port wraps around, do not try a privilege port
((startPort + offset - 1024) % (65536 - 1024)) + 1024
}
So, I'll fix the it.
