>                 URL: https://issues.apache.org/jira/browse/JENA-549
>             Project: Apache Jena
>          Issue Type: Bug
>          Components: Spatial, Text
>    Affects Versions: Jena 2.11.0
>            Reporter: Andy Seaborne
>            Assignee: Andy Seaborne
>             Fix For: Jena 2.11.1
>
>
> Example:
> {noformat}
>    ?s :p 123 .
>    ?s text:query 'foo' 
> {noformat}
> and {{text:query}} matches something, then an internal inconsistency is 
> detected by TDB.  This error happens more generally - TDB happens to have 
> additional checking code and the order of creation of concrete terms is 
> different for TDB vs in-memory execution.
> {noformat}
