[dbcp] why Jdbc2PoolDataSource.getConnection() don't return DelegatingConnection?

["Luo, Frank" <Fr...@sabre.com>]

Can someone tell me why  Jdbc2PoolDataSource.getConnection() returning a cpdsAdapter.ConnectionImpl, instead of DelegatingConnection in a non-jndi environment?

To me, it is problematic to have a fact that conn1 is not the same as conn2 in the following code:

{
//conn1 is a cpdsAdapter.ConnectionImpl
Connection conn1 = Jdbc2PoolDataSource.getConnection(); 

Statement stmt = conn1.createStatement();

//conn2 is actually an Oracle connection
Connection conn2 = stmt.getConnection();
}

Thanks.
