Valentin Kulichenko commented on IGNITE-3635:
---------------------------------------------

Fix for {{IgniteUuid}} looks good to me. In case other similar cases exist, 
let's address them separately.

> If the object field is a collection or map and one the elements in the 
> collection is that object (circular reference), stack overflow happens in 
> {{toString}} method. This happens because handles which are tracked when 
> {{toString}} is called, are lost when {{Collection.toString()}} is called. We 
> should add special handling for collections and maps and print the out 
> manually, without delegating to their {{toString()}} method.
> Test attached.
