[jira] [Created] (IGNITE-3455) Entry placed on C++ side is not found on Java side

Anton Vinogradov (Jira)
Denis Magda created IGNITE-3455:
-----------------------------------

             Summary: Entry placed on C++ side is not found on Java side
                 Key: IGNITE-3455
                 URL: https://issues.apache.org/jira/browse/IGNITE-3455
             Project: Ignite
          Issue Type: Bug
          Components: cache, platforms
            Reporter: Denis Magda
            Assignee: Denis Magda
            Priority: Blocker


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.
