OK, so you use Lazy loading, but have you detached from the transaction at
the point of serialization?
If you are still within scope of the transaction, then all that will happen
is the object serialization process will pull down all the elements of the
collection via the lazy loading strategy...
Eager loading will pull down all the entries before serialization.
To avoid either, you'd need to get your entity detached from the [entity
manager / transaction] prior to serialization...
