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

             Summary: Failed to read class name from file on deserialization
                 Key: IGNITE-2965
                 URL: https://issues.apache.org/jira/browse/IGNITE-2965
             Project: Ignite
          Issue Type: Bug
          Components: general
            Reporter: Semen Boikov
            Priority: Critical
             Fix For: 1.6


I added test MarshallerCacheJobRunNodeRestartTest from time to reproducing error 'Failed to
read class name from file' during during deserialization.

This is some issue with marshaller cache: it is updated usign putIfAbsent method, now its
implementation has a race and sometimes it can exit before value is updated on backup node.
As a workaround for marshaller cache I usggest using 'getAndPut' instead of 'putIfAbsent (just
need implement 'tryGetAndPut' method which will not wait for topology changes).

Also let's make error message in MarshallerContextImpl.className more informative.
