> Looking at the persisted state, there was an {{SshMachineLocation}} in a BYON
> location that had configuration to explicitly set the port to null.
> This meant that the call to {{getConfig(PROP_PORT)}} was returning null,
> which caused the {{NullPointerException}} during the location's
> {{toString()}}, which caused rebind to fail.
