**Android Platform API Version 22**

Beginne damit, den gemeldeten Pfad durch androidx.work.impl.WorkDatabase.onOpen, androidx.sqlite.db.framework.FrameworkSQLiteDatabase.endTransaction und androidx.work.impl.utils.ForceStopRunnable auf Android Platform API 22 nachzuverfolgen. Da der Issue keine Reproduktionsschritte oder kein erwartetes Verhalten nennt, ermittle zunächst den auslösenden Datenbankzustand und definiere den Abschluss als das Verhindern oder korrekte Behandeln dieser Rollback-Ausnahme.
