on a second thought, it will be a bit more robust if we specifically check for cancelations.
If the job was cancelled, both date and status will be already set.

if (process.getCancelled() == null) {
  process.setState(ProcessState.TERMINATED);
  process.setCompleted(LocalDateTime.now());
}

OR

if (process.getState() != ProcessState.CANCELED) {
  process.setState(ProcessState.TERMINATED);
  process.setCompleted(LocalDateTime.now());
}

Moved in the if above as the date goes along with the status

Optional: Could we only set the state message "Das Archiv wurde vollständig entpackt" when the job wasn't cancelled, too? In my opinion showing this is a bit misleading, as not all contains were extracted in that case.
