duplicated class member

While trying to generate Java objects from xsd files i can't cause scomp genereate classes with duplicate name of the member:

D:\noNamespace\InventoryChangeReferenceType.java:44: STOCK_ORDER_NUMBER is already defined in noNamespace.InventoryChangeReferenceType
static final noNamespace.ReferenceType.Enum STOCK_ORDER_NUMBER = noNamespace.ReferenceType.STOCK_ORDER_NUMBER;

D:\noNamespace\InventoryChangeReferenceType.java:74: INT_STOCK_ORDER_NUMBER is already defined in noNamespace.InventoryChangeReferenceType
static final int INT_STOCK_ORDER_NUMBER = noNamespace.ReferenceType.INT_STOCK_ORDER_NUMBER;

and I have in java file:

....
42: static final noNamespace.ReferenceType.Enum REFERENCE_TEXT = noNamespace.ReferenceType.REFERENCE_TEXT;
43: static final noNamespace.ReferenceType.Enum STOCK_ORDER_NUMBER = noNamespace.ReferenceType.STOCK_ORDER_NUMBER;
44: static final noNamespace.ReferenceType.Enum STOCK_ORDER_NUMBER = noNamespace.ReferenceType.STOCK_ORDER_NUMBER;
45: static final noNamespace.ReferenceType.Enum SUPPLIER_CLAIM_NUMBER = noNamespace.ReferenceType.SUPPLIER_CLAIM_NUMBER;
....
....
72: static final int INT_REFERENCE_TEXT = noNamespace.ReferenceType.INT_REFERENCE_TEXT;
73: static final int INT_STOCK_ORDER_NUMBER = noNamespace.ReferenceType.INT_STOCK_ORDER_NUMBER;
74: static final int INT_STOCK_ORDER_NUMBER = noNamespace.ReferenceType.INT_STOCK_ORDER_NUMBER;
75: static final int INT_SUPPLIER_CLAIM_NUMBER = noNamespace.ReferenceType.INT_SUPPLIER_CLAIM_NUMBER;
