Chandan V.A commented on OLINGO-245:
------------------------------------
Hi,
the issue is fixed now. The issue was occurring due to name conflicts between
the entity property representing the foreign key and the navigation property.
Now the entity property representing foreign key will be prefixed with FK_.
I hope this solves the issue.

> I dont know how to fix this but because of this behavior we can't just use
> {{ODataJPAContext.setDefaultNaming(false)}} for ManyToOne fields.
> I attach a simple maven project with my Entities and simple servlet for run
> in tocmat. Problematic entity is {{Products}}.
