Beginne mit den gemeldeten Einstiegspunkten MavenBuilderImpl.processBuildResults und ProjectsManager.runInWorkspace und verfolge dann die Aktualisierung der Maven-Projektkonfiguration, die den null-Aktivator erzeugt. Untersuche außerdem AccessRuleParticipant und ExecutionEnvironment im Hinblick auf die InvalidRegistryObjectException. Als abgeschlossen gilt die Reproduktion des Workflows, der den Log-Eintrag auslöst, und die Beseitigung dieser Fehler, mit einem Regressionstest, falls der relevante Testort identifiziert wird.
