Andrey Gura commented on IGNITE-602:
------------------------------------
[~SomeFire], I don't like that for every reference type instance
{{ObjectWithPosition}} object will be created. It creates additional redundant
pressure to GC. Also it seems that list is inappropriate data structure for
reference tracking because it requires O(n) operation in order to check whether
object is saved or not. It seems that {{IdentityHashMap}} is better choice for
this purpose.
