> In 10.2, an error message for a deadlock would look like this:
> ERROR 40001: A lock could not be obtained due to a deadlock, cycle of locks and waiters
is:
> Lock : ROW, T, (1,8)
>   Waiting XID : {235, S} , APP, select * from t where id = 2
>   Granted XID : {238, X} 
> Lock : ROW, T, (1,7)
>   Waiting XID : {238, S} , APP, select * from t where id = 1
>   Granted XID : {235, X} 
> . The selected victim is XID : 235.
> On trunk, the same deadlock would be reported as
> java.sql.SQLException: A lock could not be obtained due to a deadlock, cycle of locks
and waiters is:
> Lock : ROW, T, (1,8)
>   Waiting XID : {org.apache.derby.impl.services.locks.LockSpace@94884d, S} 
>   Granted XID : {org.apache.derby.impl.services.locks.LockSpace@da6bf4, X} 
> Lock : ROW, T, (1,7)
>   Waiting XID : {org.apache.derby.impl.services.locks.LockSpace@da6bf4, S} 
>   Granted XID : {org.apache.derby.impl.services.locks.LockSpace@94884d, X} 
> . The selected victim is XID : org.apache.derby.impl.services.locks.LockSpace@94884d.
> That is, the transaction id and the failing statement are not shown.
