Beginne bei AbstractDynamicStateManager.java in Zeile 704 und verfolge createEmbeddedSubProcessAndExecutions bis durch doMoveExecutionState. Stelle den gezeigten Aufruf von ChangeActivityStateBuilder nach, identifiziere den null-Wert während des Verschiebens zur Subprozessaktivität und verifiziere, dass die Operation ohne die gemeldete NullPointerException abgeschlossen wird.
