-------------------------------------
Isn't a better solution to retry a different ephemeral port on Connection
error?
> JMX port collisions in JmxServer

> org.apache.samza.metrics.JmxServer gets an ephemeral port for the registry
> but does a simple +1 to get the server port. This seems to cause occasional
> port collisions and should be improved.
> Here's the offending line:
> val serverPort = registryPort + 1 // In comparison to the registry port. Tiny
> chance of collision. Sigh.
