Blocker Description
Problem
See GridCacheMapEntry class. There are lots of calls to store like this:
cctx.store().put(null, keyValue(false), CU.value(val, cctx, false), ver);
When keyValue() is called, it might force object deserialization. And if there is no class on the server, the following exception might appear:

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