A new item type was added to an items.xml file named CarProcessDefinition. After the Ant build and SAP Commerce server startup, the following appears in the log file:15:56:54 **** [java] [m[0;31mERROR [main] [DefaultModelConverterRegistry] code CarProcessDefinition does not belong to known type. Maybe you have added a new type without updating your system.What does this message mean?
