> Fix broken Binary Object size calculation for enum objects
> ----------------------------------------------------------
>
>                 Key: IGNITE-26863
>                 URL: https://issues.apache.org/jira/browse/IGNITE-26863
>             Project: Ignite
>          Issue Type: Task
>            Reporter: Mikhail Petrov
>            Assignee: Mikhail Petrov
>            Priority: Minor
>             Fix For: 2.18
>
>          Time Spent: 40m
>  Remaining Estimate: 0h
>
> The problem can be reproduced with BinaryEnumsSelfTest.testInstanceFromBytes 
> test.
> See 
> https://ci2.ignite.apache.org/project.html?projectId=IgniteTests24Java8&testNameId=991346249142798774&tab=testDetails
> The failures are caused by an incorrect implementation of the 
> org.apache.ignite.internal.binary.BinaryEnumObjectImpl#size method, which 
> actually reads random bytes from the heap - the enum is not serialized like a 
> custom Java object (with header, footer, etc.), so using the 
> GridBinaryMarshaller.TOTAL_LEN_POS offset will point beyond the bounds of the 
> array that stores the serialized enum.
