Description

At some parts Olingo does not use the fully qualified name of a resource to reference it.Therefore pojogen fails when you have a resource with the same name as a value defined in EdmPrimitiveTypeKind.java. Take the following scenario:
$metadata

...
<EntityType Name="Binary">
  <Property Name="asset" Type="Edm.Int64"/>
  <Property Name="version" Type="Edm.Int64"/>
  <Property Name="type" Type="Edm.String"/>
  <Property Name="format" Type="Edm.String"/>
</EntityType>
...

My self.edu.Binary resource match with the primitive kind Edm.Binary due to the check in EdmTypeInfo.java:

this.primitiveType = EdmPrimitiveTypeKind.valueOf(this.fullQualifiedName.getName());

When the code generator tries to access the type of the entity it throws a NullPointerException.
