javadoc typo in OracleCollectionAdmin.createIndex()

Minor javadoc bug in OracleCollectionAdmin. createIndex(): "an error occurs while dropping the index" should probably be "while creating the index"

  /**
   * Create an index using an index specification (expressed in JSON).
   * 
   * @param indexSpecification       an index specification. Cannot be
   *                                 <code>null</code>
   * @throws OracleException         if (1) the index specification is
   *                                 <code>null</code>, or (2) an error
   *                                 occurs while dropping the index

  public void createIndex(OracleDocument indexSpecification)
    throws OracleException;
