Amelchev Nikita commented on IGNITE-6692:
-----------------------------------------
I’ve fixed the issue.
Description of the problem: We can build a binary object without fields in the
binary object builder. If we don't add a field, SchemaId will be set to zero.
When we try to read field value, marshaller will try to find this schema and
throw an exception.
It was fixed by introducing of a new check on schemaId and when it equals to
zero then the field value will return null.
Please, [review the
changes|https://reviews.ignite.apache.org/ignite/review/IGNT-CR-381].
[Tests|https://ci.ignite.apache.org/project.html?projectId=Ignite20Tests&tab=projectOverview&branch_Ignite20Tests=pull%2F2918%2Fhead]
look good.
