Hi,

While trying to find a query that works and performs well enough I
noticed that this query:

PREFIX skos: <http://www.w3.org/2004/02/skos/core#>
PREFIX text: <http://jena.apache.org/text#>

SELECT *
WHERE {
   GRAPH ?graph {
     ?s text:query 'musiikkikasv*' .
   }
}
VALUES ?graph { <http://www.yso.fi/onto/yso/> }

when there are any potential results, produces this error:

Error 500: Attempt to reassign '?graph' from
'<http://www.yso.fi/onto/yso/>' to '<http://www.yso.fi/onto/yso/>'


I guess this is a bug related to jena-text, since a basic graph pattern
instead of the text:query pattern works.

If I change ?graph to the actual URI and remove the VALUES clause, then
there is no error.

This also happens with 1.3.0 so this is not a new bug.

Fuseki - version 1.3.1-SNAPSHOT (Build date: 2015-12-06T09:53:42+0000)



Stacktrace?
