Patrick Linskey reopened OPENJPA-370:
-------------------------------------


It looks like this patch might have a performance impact due to the additional time required to compute field inclusion. We should consider other implementation routes or potentially rolling this back on the 1.0.x branch prior to 1.0.1, depending on what we decide our release criteria should be.

> Employee class has a LoadFetchGroup annotation defined on the Rating field, when getRating was called, the address should be returned also. However, openjpa did not handle the LoadFetchGroup correctly, therefore, address was not eargly fetched.
> public class FGEmployee{
>     @Id
>     private int id;
>  
>     @OneToOne(fetch=FetchType.LAZY) 
>     private FGAddress address;
>  
>     @Basic(fetch=FetchType.LAZY)
>     @LoadFetchGroup("AddressFetchGroup")
>     private String rating;
