>             Project: Teiid
>          Issue Type: Bug
>          Components: Query Engine
>    Affects Versions: 6.3.0
>            Reporter: Van Halbert
>            Assignee: Steven Hawkins
>            Priority: Minor

> Running integration test:  testMultipleSourceMultipleCommandsCancel
> When the query is cancelled, the following exception is seen:
> java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
> 	at java.util.ArrayList.RangeCheck(ArrayList.java:547)
> 	at java.util.ArrayList.get(ArrayList.java:322)
> 	at com.metamatrix.query.processor.relational.BatchedUpdateNode.open(BatchedUpdateNode.java:95)
> 	at com.metamatrix.query.processor.relational.RelationalNode.open(RelationalNode.java:236)
> 	at com.metamatrix.query.processor.relational.RelationalPlan.open(RelationalPlan.java:101)
> Just worried that if the process doesn't clean up properly, it may cause a memory leak or have some latent effect.
