Fixed version (ground truth):

        }
        DataAwareEntryEvent dataAwareEntryEvent=(DataAwareEntryEvent)event;
        Data key=dataAwareEntryEvent.getKeyData();
        Data value=dataAwareEntryEvent.getNewValueData();
        Data oldValue=dataAwareEntryEvent.getOldValueData();
        PortableEntryEvent portableEntryEvent=new PortableEntryEvent(key,value,oldValue,event.getEventType(),event.getMember().getUuid());
