>             Project: Apache Jena
>          Issue Type: Bug
>          Components: TDB
>    Affects Versions: TDB 0.9.4

> TDB is producing incorrect results processing queries containing FILTER NOT EXISTS clauses with an inner filter, such as
> PREFIX : <http://example.com/>
> SELECT * WHERE {
>         ?x :p ?n
>         FILTER NOT EXISTS {
>                 ?x :q ?m .
>                 FILTER(?n = ?m)
>         }
> }
> an example taken from the spec.  In this case it produces no results when it should produce one.
> I'll attach a test case in moment - which produces the correct result when the query is run on a memory model and incorrect one (no results) when run on TDB.
