Description

QueryIterMinus calculates the right table in its constructor, that is, while the query iterator tree is being built.

If this is happening during getPlan().iterator() in QueryExecuteBase (Jena 4.1.0) (or QueryExecDataset for the reorganised code) then the top level iterator isn't set until the entire iterator tree has been built, and so can't propagate the cancel.

Report: Cristóbal Miranda on users@.
