> Ticket is created according to dev list discussion:
> http://apache-ignite-developers.2346864.n4.nabble.com/Fwd-Data-Loss-while-upgrading-custom-jar-from-old-jar-in-server-and-client-nodes-td28808.html
> Cache configuration is serialized by JDK marshaller and persisted in
> cache_data.dat file. It may contain instances of classes that disappeared
> from runtime classpath (e.g. if implementation of CacheStore has been
> renamed). In such case, node will fail on start.
> We should handle this and show meaningful message with instruction how to
> overcome this issue - delete cache_data.dat and restart cache.
