/**
 * {@link NativeJdbcExtractor} implementation that delegates to JDBC 4.0's
 * <code>unwrap method, as defined by {@link java.sql.Wrapper}.
 *
 * <p>Note: Only use this when actually running against a JDBC 4.0 driver,
 * with a connection pool that supports the JDBC 4.0 API (i.e. at least accepts
 * JDBC 4.0 API calls and passes them through to the underlying driver)!
