Andy Seaborne commented on JENA-630:
------------------------------------
(minor) The commit has:
{noformat}
+ } catch (ARQInternalErrorException ex) {
+ // May show up when trying to fold certain things
+ return copy(newArgs);
{noformat}
dare I ask what causes ARQInternalErrorException?
> Do constant folding as part of query optimisation

> Components: ARQ
> Affects Versions: Jena 2.11.1
> Reporter: Rob Vesse
> Assignee: Rob Vesse
> Fix For: Jena 2.11.2

> baked into it.
> This issue will track work to integrate a transform for this into the
> standard optimiser.
