Denis Magda commented on IGNITE-3455:
-------------------------------------

Igor, thanks.

Comments from my side.

1. I would rename the page to "Platform Interoperability" as it's done for .Net 
[1] and place it under "Basic Concept" section.

2. In this section [2] it's better to split "Tab" based examples (Java, C++ and 
XML) on step-by-step guidance: a) this is what must be done on C++ side; b) 
this is exemple code for Java; c) and this is XML configuration for C++ while 
that is for Java.

> If a custom key is used for cache values then the following scenario doesn't 
> work:
> - value is placed on C++ side;
> - value is read on Java side (value is not found here).
> Reverse direction is not workable as well.
> HashCode is implemented properly in C++ and Java.
> Fast debugging showed that a partition and primary node is calculated 
> properly. Looks like that there is a serialization related issue that leads 
> to the situation when "equals" fails during an object lookup.
