Unexpected flag value

Tue, 28 Feb 2017 21:28:09 -0800 

Hi,

i am seeing *class org.apache.ignite.binary.BinaryObjectException:
Unexpected flag value *when i run a query.

What could be the actual root cause of this issue ? i have attached the
complete stack trace.

But the query is running fine when i run explicitly.

I can provide the sudo code for the scenario if required. thanks,

Thanks.
