…h a null value

(OFBIZ-11143)

When you write an entity condition like
  rawProdcuts = from(Product).where(
    EntityCondition.makeCondition(EntityOperator.AND,
       'productTypeId', 'RAW_MATERIAL',
       'quantityUomId', null)
    ).queryList()

the function

  public static EntityFieldMap makeCondition(EntityJoinOperator joinOp, Object... keysValues) 

raise a IllegalArgumentException

The problem came from EntityUtil.makeFields(V... args) (EntityUtil.java:65) who check if a value is an insteance of Comparable and Serializable but didn't take the case tat where have a null value.

Thanks to Pawan Verma for the review
