            Assignee: Sergey Antonov
             Fix For: 2.8


Scenario:
 * Start server node with predefined cache and activate cluster.
 * Connect thin java client to cluster
 * Put entry to the cache with user defined key (custom class) from server node.
 * Try get value from thin client by the same key. 

Expected:
