Milosz Tylenda resolved OPENJPA-1691.
-------------------------------------

    Fix Version/s: 2.1.0
       Resolution: Fixed

The fix requires a JDBC 4 driver. There are still issues when querying over long individual XML nodes coming from obscure limits in Oracle's extractValue() function.

Note that reading XML values longer than 4000 bytes was also broken - replaced getStringVal() calls with getClobVal().

As a side effect users gained a bit of control on INSERT/UPDATE statements in DBDictionary.getMarkerForInsertUpdate method.
