Amelchev Nikita commented on IGNITE-6692:
-----------------------------------------

[~vozerov], I have done a check to existing schema through the BinaryUtils.FLAG_HAS_SCHEMA flag. 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. [Tests|https://ci.ignite.apache.org/project.html?projectId=Ignite20Tests&tab=projectOverview&branch_Ignite20Tests=pull%2F2918%2Fhead] look good.
