Statement cancelled, probably by transaction timing out

According to the below article, Oracle recommond normal(e.g. thin) DB driver over XA drivers. Presentation

In recent days/weeks I'm getting multiple requests with questions of following type: I have a problem with the rollback, I'm working with weblogic 10.3.6. In my application back when I do a rollback, but at the launch of the back gives me this error - java.sql.SQLException: Statement cancelled, probably by transaction timing out and similar. People are facing this issue when they move application to production or test server, on development environment embedded WebLogic everything works fine.

But really this is not an issue at all. What happens is - WebLogic administrators define wrong data source (XA data source). Error is not reproduced on embedded WebLogic, because data source is created automatically for you in development environment. XA data source should be never user with ADF/Fusion applications because it closes all cursors upon commit.
