      When an entity is defined as following (unique index annotation on the primary key field. In this situation):

      public class AddressBeanAno implements IAddressBean, Serializable {
      private AddressPK street;

      Informix will issue an error:

      Caused by: org.apache.openjpa.lib.jdbc.ReportingSQLException: Index already exists on column.

      {stmnt 1440372186 CREATE UNIQUE INDEX street_index ON AddressBean (street)}

      Per Informaix SQL syntax guide (Create Index section):
      You can not add a unique index to a column or column list that a primary -key constraint on it. The reason is that defining the column or column list as the primary key causes the database server to create a unique internal index on the column or column list. So you cannot create another unique index on this column or column list with CREATE INDEX statement.
