Subject Re: IGNITE-6692 Select query on a client with unused field throws an exception.

Thanks for the comments.

I have done check to the existing schema through the
BinaryUtils.FLAG_HAS_SCHEMA flag [1].

Also, I have checked other places where we can try to read not initialized
schema and found that BinaryObjectBuilderImpl.ensureReadCacheInit() method
can do it. If we try to get from the BinaryObject, which contains no
fields, any field through BinaryObjectBuilder, it will throw an exception.
I have fixed this bug and suggest to include it in this issue. Please,
review [2]. Tests look good [3].
