/**
* A {@link Jdbc4NativeJdbcExtractor} which comes pre-configured for Oracle's JDBC driver,
* specifying the following vendor-specific API types for unwrapping:
* <ul>
* <li><code>oracle.jdbc.OracleConnection</code>
* <li><code>oracle.jdbc.OracleStatement</code>
* <li><code>oracle.jdbc.OraclePreparedStatement</code>
* <li><code>oracle.jdbc.OracleCallableStatement</code>
* <li><code>oracle.jdbc.OracleResultSet</code>
* </ul>
*
* <p>Note: This will work with any JDBC 4.0 compliant connection pool, without a need for
* connection pool specific setup. In other words, as of JDBC 4.0, NativeJdbcExtractors
* will typically be implemented for specific drivers instead of for specific pools.
