Krzysztof commented on IGNITE-6234:
-----------------------------------

Hi,
I'm facing this issue to, but in slightly different scenario. 

However I wonder how *schemaIds *can be null since *BinaryMetadata *constructor sets this
field to *Collections.emptySet();* in a "worst" case.

> 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
