> .NET: Incorrect binary object hash code calculation
> ---------------------------------------------------
>
> Key: IGNITE-5455
> URL: https://issues.apache.org/jira/browse/IGNITE-5455
> Project: Ignite
> Issue Type: Bug
> Components: platforms
> Affects Versions: 2.0
> Reporter: Pavel Tupitsyn
> Assignee: Pavel Tupitsyn
> Priority: Critical
> Labels: .NET
> Fix For: 2.1
>
>
> Hash code is calculated over binary object data with the following code in
> Java and .NET:
> {code}
> for (int i = start; i <= end; i++)
> hash = 31 * hash + data[i];
> {code}
> Where {{data}} is {{byte[]}} in Java and .NET.
> And {{byte}} is signed in Java and unsigned in .NET.
> So in our simple tests on small values it works, but fails on real world data.
> As a result, for non-primitive keys:
> * DML is broken
> * Java interop is broken
