/**
* Implementation of the NativeJdbcExtractor interface for ObjectWeb's XAPool.
*
* Returns underlying native Connections and native PreparedStatements to
* application code instead of XAPool's wrapper implementations; unwraps the
* Connection for native Statements and native CallableStatements.
* The returned JDBC classes can then safely be cast, e.g. to
* oracle.jdbc.OracleConnection.
*
*
This NativeJdbcExtractor can be set just to allow working with
* an XAPool DataSource: If a given object is not an XAPool wrapper, it will
* be returned as-is.
