>             Project: JBoss Application Server
>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>          Components: JCA service
>            Reporter: Vicky Kak

> The JCA lazy initialization does not work in the following sceanrio
> *********************************************************************
>  DataSource ds = ...
>  Connection c = ds.getConnection();
>  UserTransaction ut = ...
>  ut.begin(); 
>  // Do work
>  c = ds.getConnection(); // This should be avoided and looks antipattern.
>  ut.commit();
>  ut.begin(); 
>  *********************************************************************
>  
>  Getting the connection again in the TX context causes the issue, the subsequent 
>  ds.getConnection() leads to multiple enlistment of the local XAResources 
>  and thus causing this warning
>  http://www.jboss.org/community/wiki/Multiple1pc
> The application developers should not follow the above coding pattern, however we should fix the issue cropping due to this coding practice as it could lead some  misbehaviour in container, there are no evidences about the misbehaviour but it had been reported by our customers.
