> Query returning 2 entities w/1-1 relationship returns [Address, Address]  instead of [Winery, Address]
> "SELECT r,r.address from Winery r" returns [Address, Address] 
> "SELECT r,r.home from EmpBean r" returns [null, AddressBean] 
> does not matter if 1-1 relationship is uni-directional or bi-directional
> (NOTE: "SELECT r.address,r" gets same Address id already exists in the L1 cache  if uni-dir relationship (issue 209))
