Maybe use a constant for the `/messages` endpoint?

Review Comment:
If possible, try not to use a fixed port as it breaks the tests on some CIs
if the port is used (and, also, 443 is a privileged port that would require
root access). Take a look at the `AvailablePortFinder` class for this.

I think you can use `ObjectHelper.notNull` here.

Review Comment:
Is there a change of `service` being `null` here? It does not look like the
case, so ... just double checking.

Review Comment:
Header constants, if they are available in one of the libraries in use, can
make the code easier to read/maintain.
