> hibernate initializes lazy objects traversed by the persist operation; 
> for example, in this case (the project is attached):
> class A has bidirectional one-to-many relationship to classes B1, B2, B3, B4 
> (b1List, b2List, b3List, b4List) 
> B1 has bidirectional one-to-many relationship to C1 
> (c1List) 
> B2 has bidirectional one-to-many relationship to C2 
> (c2List) 
> if we try persisting C2, it will also initialize B1, C1, B4 ... and other existing C2's
