[ https://svn.apache.org/r1526459 ]
JENA-549 : Ground subject and object PropFuncArg before use.
Add checking code to QueryIterExtendByVar
> Subject variables in a text:query bound earlier in the query cause exception
> in TDB.
> ------------------------------------------------------------------------------------

> Key: JENA-549
> 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
>
> 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}
