> Reporting for Mamta Satoor, filed on Derby-dev list.
> I think there is a bug in Derby when the user code tries to get the
> Connection object from XAConnection "inside" the global transaction.
> In this case, the Connection object gets created with un-supported
> holdability. Look at the following piece of code and it's output to
> see what exactly happens
>     EmbeddedXADataSource dscsx = new EmbeddedXADataSource();
>     dscsx.setDatabaseName("wombat");
>     XAConnection xac = dscsx.getXAConnection("fred", "wilma");
>     XAResource xr = xac.getXAResource();
>     xid = getXid(27, (byte) 21, (byte) 01);
>     xr.start(xid, XAResource.TMNOFLAGS);
>     conn1 = xac.getConnection();
>     System.out.println("This is a bug. Connection's holdability should
> have been CLOSE_CURSORS_AT_COMMIT since it is in the global
> transaction");
>     System.out.println("CONNECTION(in xa transaction) HOLDABILITY " +
> (conn1.getHoldability() == ResultSet.HOLD_CURSORS_OVER_COMMIT));
>     System.out.println("Autocommit on Connection inside global
> transaction has been set correctly to " + conn1.getAutoCommit());
>     xr.end(xid, XAResource.TMSUCCESS);
> The output for the above piece of code is
>     This is a bug. Connection's holdability should have been
> CLOSE_CURSORS_AT_COMMIT since it is in the global transaction
>     CONNECTION(in xa transaction) HOLDABILITY true
>     Autocommit on Connection inside global transaction has been set
> correctly to false
