GetCollectionMetaData: this method is not supported by 'OracleXMLDataSetGenJdbc' cla

Question

The following Java code:
// Create an OracleOCIConnectionPool instance with default configuration
OracleOCIConnectionPool cpool = new OracleOCIConnectionPool("appserver", "9ias", url, null);
// Print out the default configuration for the OracleOCIConnectionPool
System.out.println ("-- The default configuration for the OracleOCIConnectionPool --");
displayPoolConfig(cpool);
// Get a connection from the pool
OracleOCIConnection conn1 = (OracleOCIConnection) cpool.getConnection("usecase", "uml");
// Create a Statement
Statement stmt = conn1.createStatement ();
// Select the ENAME column from the EMP table
ResultSet rset = stmt.executeQuery ("select * from usecases_ov");
OracleXMLQuery q = new OracleXMLQuery(conn1,"select * from usecases_ov");
System.out.println(q.getXMLString());
Produces:
-- The default configuration for the OracleOCIConnectionPool --
Min poolsize Limit: 1
Max poolsize Limit: 1
Connection Increment: 0
NoWait: false
Timeout: 0
PoolSize: 1
ActiveSize: 0
<?xml version = '1.0'?>
<ERROR>oracle.xml.sql.OracleXMLSQLException: getCollectionMetaData: this method is not supported by 'OracleXMLDataSetGenJdbc' class. Please use 'OracleXMLDataSetExtJdbc' instead.</ERROR>
Any Suggestions?

One import piece of info: This OracleXMLQuery works against a standard table. The query that fail goes against the following view and uses nested tables(object lists).
SELECT v.name as PACKAGE,
u.name,
u.version,
u.iteration,
u.summary,
u.events_basic,
u.author,
u.rev_date,
u.ext_points,
u.assumptions,
u.preconditions,
u.revision_notes,
u.trigger_event,
u.package as PUID,
u.ALTERNATE_PATHS AS ALTERNATE_PATHS_LIST,
u.EXCEPTION_PATHS AS EXCEPTION_PATHS_LIST,
u.BUSINESS_RULES AS BUSINESS_RULE_LIST
FROM USECASE u, DESIGN_PACKAGE v
WHERE u.package=v.puid
AND EXISTS(SELECT 'X'
     FROM DESIGN_CUR_VER d
     WHERE d.name = u.name
     AND d.version = u.version
     AND d.design_date = u.rev_date)
AND EXISTS (SELECT 'X'
     FROM USECASE_AUDIT a
     WHERE a.package = u.package
     AND a.name = u.name
     AND a.version = u.version
     AND a.timestamp = u.rev_date
     AND a.status_code IN('created','modified','rejected'))
ORDER BY v.name, u.name
