Andy Seaborne commented on JENA-1947:
-------------------------------------
Not fine - a mysterious stack overflow isn't a good experience.
There isn't a meaning, especially when cycle does not "move" the validation to
a different place in the graph with a property shape.
So warning or error,
(My working solution is to combine cycle detection with putting in a special
internal shape for "no validation due to cycle" in the evaluation tree).
> SHACL validator: Stack overflow on recursive shapes even if deactivated

> Project: Apache Jena

> Components: SHACL
> Reporter: Jan Rosecky
> Priority: Major

> I'm trying to validate using a set of shapes including:
> [http://purl.allotrope.org/shapes/adm/core/REC/2020/06/common.shapes] .
> af-s:AFS_0000001 has a recursive sh:and(af-s:AFS_0000001) clause, which
> causes a stack overflow exception - even though the shape is sh:deactivated.
