fuseki fails to upload data to memory but sucess to TDB

I have this free Ontology

http://protege.cim3.net/file/pub/ontologies/wine/wine.owl

I can not load it when using in memory service, but I can load it when using TDB service.

This is my config

@prefix :        <#> .
@prefix fuseki:  <http://jena.apache.org/fuseki#> .
@prefix rdf:     <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix rdfs:    <http://www.w3.org/2000/01/rdf-schema#> .
@prefix ja:      <http://jena.hpl.hp.com/2005/11/Assembler#> .
@prefix tdb:     <http://jena.hpl.hp.com/2008/tdb#> .

[] rdf:type fuseki:Server ;
    fuseki:services (
 <#serviceInMemoryWithReasoner>
    )
.

# TDB
    tdb:DatasetTDB  rdfs:subClassOf  ja:RDFDataset .
    tdb:GraphTDB    rdfs:subClassOf  ja:Model .

[] ja:loadClass "com.hp.hpl.jena.tdb.TDB" .

# ------ In memory with reasoner
<#serviceInMemoryWithReasoner> rdf:type fuseki:Service;
    rdfs:label "testdataset";
    fuseki:name "testdataset";
    fuseki:serviceQuery "query";
    fuseki:serviceUpdate "update";
    fuseki:dataset <#datasetServiceInMemoryWithReasoner> ;
.

<#datasetServiceInMemoryWithReasoner> rdf:type ja:RDFDataset;
    ja:defaultGraph <#datasetmodelServiceInMemoryWithReasoner>
.

<#datasetmodelServiceInMemoryWithReasoner>
    ja:reasoner [ ja:reasonerURL <http://jena.hpl.hp.com/2003/OWLFBRuleReasoner>];
.

Am i doing something wrong?

the problem that I am getting is:

Again, loading the same file using TDB is working

It appears that you are running a version of Fuseki that does not recognize .owl. Try changing the file extension to .rdf.

(edited due to additional information)

The latest released version, 2.3.1, recognizes .owl.

The TDB service and memory service are presumably differently defined.

The service configuration shown does not have a loading service.

http://jena.apache.org/documentation/fuseki2/fuseki-configuration.html

For loading from the UI, you need the fuseki:serviceReadWriteGraphStore (it uses the SPARQL Graph Store Protocol).
