Andrus, thanks for comment. Your idea better for issue. So, here is the next patch. Expression will contain ObjectId instead of whole Persistent object, whereupon we get rid from serialize fault objects.

> If entity is used as a parameter in qualifier expression all its unfaulted to-many relationships are faulted prior to actual query sent to server. For example:
> Expression exp = ExpressionFactory.matchExp(Painting.ARTIST_PROPERTY, artist);
> context.performQuery(new SelectQuery(Painting.class, exp));
> Before actual query will be sent to server all artist's to-many relationships will be faulted. What I see is that in the process of query serialization on client side PersistentObjectList.size() is invoked which triggers relationships' faulting from database.
