Description

It seems like the implementation of the method UriParserImpl#handleSystemQueryOptionExpand has a flaw. At L#792 where the property of type EdmTyped gets fetched, it looks like the attribute edmType of property will always be null and therefore the check afterwards throws a NullPointerExcpetion which is then handled by an OData Common Exception.

That has to be the reason why expand is not working.. despite decent looking Navigation Properties.
