-------------------------------------------------------------
I'm using the docker image stain/jena-fuseki .
It appears to just run the basic fuseki-server script. The /logs folder is
empty however.

> Key: JENA-1522
> URL: https://issues.apache.org/jira/browse/JENA-1522
> Project: Apache Jena
> Issue Type: Bug
> Components: Fuseki, Jena
> Affects Versions: Jena 3.6.0
> Environment: System 1: Centos 7, Jena 3.6, Unknown Fuseki version.
> System 2: Ubuntu 16.04 running Docker. Running stain/jena-fuseki from the

> Priority: Critical
>
> In my 500M+ triple dataset, queries seem to be failing for no clear reason.
> Here's an example.
> {code:java}
> prefix Products: <http://www.example.com/test/Products#>
> select ?p ?o
> where {
> Products:ABC ?p ?o .
> }
> {code}
> ...results in a list like:
> {code:java}
> Products:HasComponent Products:DEF
> Products:HasComponent Products:GHI {code}
> Now running this query:
> {code:java}
> prefix Products: <http://www.example.com/test/Products#>
> select ?p
> where {
> Products:ABC ?p Products:DEF .
> } {code}
> ...has no results. How is this possible?
>
> Here's another example.
> {code:java}
> prefix Products: <http://www.example.com/test/Products#>
> ask where {
> Products:ABC Products:PartNumber ?p .
> filter ( ?p = "ABC" )
> } {code}
> This returns "True"
>
> {code:java}
> prefix Products: <http://www.example.com/test/Products#>
> ask where {
> ?s Products:PartNumber ?p .
> filter ( ?p = "ABC" )
> } {code}
> This returns "False"
>
> What other info can I provide?
