---------------------------------------

             Summary: Binary object might be deserialized unexpectedly when cache store is enabled.
                 Key: IGNITE-2753
                 URL: https://issues.apache.org/jira/browse/IGNITE-2753
             Project: Ignite
          Issue Type: Bug
          Components: cache
    Affects Versions: 1.5.0.final
            Reporter: Vladimir Ozerov
            Assignee: Dmitry Karachentsev
            Priority: Critical
             Fix For: 1.6


*Problem*
See {{GridCacheMapEntry}} class. There are lots of calls to store like this:
{code}
cctx.store().put(null, keyValue(false), CU.value(val, cctx, false), ver);
{code}

When {{keyValue()}} is called, it might force object deserialization. And if there is no class on the server, the following exception might appear:
{code}

{code}

*Proposed solution*
Pass key and value directly to store manager. It should already handle everything correctly.
