Amelchev Nikita updated IGNITE-17042:
-------------------------------------
    Description: 
There are several tests that failed due to client cache is null:
{noformat}
grid(0).createCache(ccfg);
clientCache = client.cache(ccfg.getName()); 

clientCache.put(); // Cache can be null due to client registers cache 
asynchroniously.
{noformat}

Example of test: CacheEntryProcessorNonSerializableTest.testPessimisticFullSync

{noformat}
