Code Ferret commented on JENA-1439:
-----------------------------------
Never flippin mind. located the error. I missed the {{List.remove}} at line
143/144 in {{TetQueryPF.extractArg}}.
Either the list needs to be cloned or more likely the remove simply needs to be
removed, since as coded it is side-effecting the {{List<Node>}} bound in the
{{OpPropFunc}} used in the graph iteration
> graph queries fail to preserve text:query 'lang:xx' arg

> Jena-text queries that iterate over graphs, such as:
> {code}
> select ?g ?s ?lit
> where {
