XMLElement nesting limit?

Question

Hopefully I can ask this in a way that makes sense. I have a very basic query I have been working with to extract data and wrap it in XML. This query runs fine from the command line but when executing via JDBC if I exceed 20 nested elements each row returned in the result set is truncated to 48 characters almost all of which are null code=0 when viewed in hex. DB is 10.2.0.4. Driver is ojdbc6_g.jar. jdk is 1.6.0_19. Any ideas? Thx
SELECT
XMLElement("Item",
XMLElement("TEST1", 'Some test data'),
XMLElement("TEST2", 'Some test data'),
XMLElement("TEST3", 'Some test data'),
XMLElement("TEST4", 'Some test data'),
XMLElement("TEST5", 'Some test data'),
XMLElement("TEST6", 'Some test data'),
XMLElement("TEST7", 'Some test data'),
XMLElement("TEST8", 'Some test data'),
XMLElement("TEST9", 'Some test data'),
XMLElement("TEST10", 'Some test data'),
XMLElement("TEST11", 'Some test data'),
XMLElement("TEST12", 'Some test data'),
XMLElement("TEST13", 'Some test data'),
XMLElement("TEST14", 'Some test data'),
XMLElement("TEST15", 'Some test data'),
XMLElement("TEST16", 'Some test data'),
XMLElement("TEST17", 'Some test data'),
XMLElement("TEST18", 'Some test data'),
XMLElement("TEST19", 'Some test data'),
XMLElement("TEST20", 'Some test data'),
XMLElement("TEST21", 'Some test data')) AS ITEM
FROM TABLE

Apparently it is not just exceeding 20 XMLElement calls that causes the problem. It is also counting nested XMLAttribute calls as well.
SELECT
     XMLElement("Item",
          XMLElement("TEST1", XMLAttributes('Test Value' AS "Attribute"), 'Some test data'),
          XMLElement("TEST2", 'Some test data'),
          XMLElement("TEST3", 'Some test data'),
          XMLElement("TEST4", 'Some test data'),
          XMLElement("TEST5", 'Some test data'),
          XMLElement("TEST6", 'Some test data'),
          XMLElement("TEST7", 'Some test data'),
          XMLElement("TEST8", 'Some test data'),
          XMLElement("TEST9", 'Some test data'),
          XMLElement("TEST10", 'Some test data'),
          XMLElement("TEST11", 'Some test data'),
          XMLElement("TEST12", 'Some test data'),
          XMLElement("TEST13", 'Some test data'),
          XMLElement("TEST14", 'Some test data'),
          XMLElement("TEST15", 'Some test data'),
          XMLElement("TEST16", 'Some test data'),
          XMLElement("TEST17", 'Some test data'),
          XMLElement("TEST18", 'Some test data'),
          XMLElement("TEST_19", 'Some test data')) AS ITEM
FROM ITEMS
