Open iterator warning on sparql select count

[Patrick Logan]

I am executing a simple Sparql select (count(?var) as ?n) where {
simple pattern }

Doing so gets the following warning logged...

16:07:36 WARN  QueryIteratorCheck        :: Open iterator: QueryIterSingleton/7

Is this safely ignored?

This is jena-arq 2.9.0-incubating

Thanks
