When a Maven build is aborted the Sonar plug-in post-build action runs, but analysis is empty

When a Maven build is aborted, i.e. an slave is not responding on time, the Sonar plug-in post-action runs. As there are no classes, no tests and so on, the analysis is emptied in the Sonar database.

This is the console output for the job:
