Ramesh Reddy commented on OLINGO-931:
-------------------------------------
The real requirement for an entity is that it MUST be populated with its
entity id. We can avoid NPE, but it will need to be replaced with another
exception, allowing without an ID is not an option.
> $select does not work with JsonSerializer
