Valentin Kulichenko reassigned IGNITE-2105:
-------------------------------------------
Assignee: Valentin Kulichenko
> DirectMessageWriter cannot write nested collections.
> ----------------------------------------------------
>
> Key: IGNITE-2105
> URL: https://issues.apache.org/jira/browse/IGNITE-2105
> Project: Ignite
> Issue Type: Bug
> Components: 1.4
> Affects Versions: ignite-1.4
> Reporter: Vladimir Ozerov
> Assignee: Valentin Kulichenko
> Priority: Critical
> Fix For: 1.5
>
>
> Steps to reproduce:
> 1) Run GridMessageCollectionTest in ignite-1.5 branch
> 2) Observe class-cast exception.
> The problem is caused by DirectByteBufferStreamImplV2 which is re-used across
> all nested objects.
> This class is stateful. When nested collection is written, instead of writing
> collection element it writes element of another collection which is upper in
> call stack.
> Looks pretty critical for me.
