> Key: IGNITE-6234
> URL: https://issues.apache.org/jira/browse/IGNITE-6234
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.1
> Reporter: Sergey Chugunov
> Assignee: Sergey Chugunov
> Labels: MakeTeamcityGreenAgain
>
> 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|https://ci.ignite.apache.org/viewLog.html?buildId=798538&tab=buildResultsDiv&buildTypeId=Ignite20Tests_IgniteCache].
> 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:
> {noformat}
> java.lang.NullPointerException: null
