025/**
026 * A {@link Jdbc4NativeJdbcExtractor} which comes pre-configured for Oracle's JDBC driver,
027 * specifying the following vendor-specific API types for unwrapping:
028 * <ul>
029 * <li>{@code oracle.jdbc.OracleConnection}
030 * <li>{@code oracle.jdbc.OracleStatement}
031 * <li>{@code oracle.jdbc.OraclePreparedStatement}
032 * <li>{@code oracle.jdbc.OracleCallableStatement}
033 * <li>{@code oracle.jdbc.OracleResultSet}
034 * </ul>
035 *
036 * <p>Note: This will work with any JDBC 4.0 compliant connection pool, without a need for
037 * connection pool specific setup. In other words, as of JDBC 4.0, NativeJdbcExtractors
038 * will typically be implemented for specific drivers instead of for specific pools.
