> Using different namespaces for olingo annotated POJOs and the AnnotationEdmProvider may produce unparsable queries. Here is how to reproduce:
> * create model that uses 2 namespaces with navigation between entities, for example the entities {{A}} and {{B}} have namespace {{AB}}, the entities {{C}}, {{D}} have namespace {{CD}}.
> {code}
> @EdmEntityType(name = "A", namespace = "AB")
>     @EdmEntitySet(name = "AA")
>     class A {
>         @EdmKey
>         @EdmProperty
>         String id;
>         @EdmNavigationProperty(toMultiplicity = Multiplicity.ZERO_OR_ONE, toType = B.class)
>         B b;
>     }
>     @EdmEntityType(name = "B", namespace = "AB")
>     @EdmEntitySet
>     class B {
>         @EdmNavigationProperty(toMultiplicity = Multiplicity.MANY, toType = A.class)
>         List<A> a;
>     }
>     @EdmEntityType(name = "C", namespace = "CD")
>     @EdmEntitySet(name = "CC")
>     class C {
>         @EdmKey
>         @EdmProperty
>         String id;
>         @EdmNavigationProperty(toMultiplicity = Multiplicity.ZERO_OR_ONE, toType = D.class)
>         D d;
>     }
>     @EdmEntityType(name = "D", namespace = "CD")
>     @EdmEntitySet
>     class D {
>         @EdmNavigationProperty(toMultiplicity = Multiplicity.MANY, toType = C.class)
>         List<C> c;
>     }
> {code}
> * Now build the model with 
> {code}
> new AnnotationEdmProvider(Arrays.<Class<?>> asList(A.class, B.class, C.class, D.class));      
> {code}
> * The query http://localhost/CC('1')/D results in 
>  Attempt to parse these queries results in 
> {code}
> org.apache.olingo.odata2.api.edm.EdmException: An exception occurred.
> 	at org.apache.olingo.odata2.core.edm.provider.EdmEntityContainerImplProv.getAssociationSet(EdmEntityContainerImplProv.java:169)
> 	at 
> ...
> {code}
> I guess the reason is that the default namespace container is generated in the wrong schema (the schema for the last entities in the list)
> This issue is blocking our development.
