Description
Test reproducible locally although with a very low probability.
I wasn't able to reproduce it starting test in isolation but managed to do it starting GridCacheClientModesTcpClientDiscoveryAbstractTest 50 times in a row observing from 1 to 3 failures.
Test run with failed test is available here.
It seems that when client requests value of custom class from near cache it may see BinaryMetadata for this class with no schema.
Test fails with the following exception:
java.lang.NullPointerException: null

Quick fix: add null check for schemaIds.
