> kryo serialization problem

> Key: FLINK-2800
> URL: https://issues.apache.org/jira/browse/FLINK-2800
> Project: Flink
> Issue Type: Bug
> Components: Type Serialization System
> Affects Versions: 0.10
> Environment: linux ubuntu 12.04 LTS, Java 7
> Reporter: Stefano Bortoli
> Assignee: Till Rohrmann

> Performing a cross of two dataset of POJOs I have got the exception below.
> The first time I run the process, there was no problem. When I run it the
> second time, I have got the exception. My guess is that it could be a race
> condition related to the reuse of the Kryo serializer object. However, it
> could also be "a bug where type registrations are not properly forwarded to
> all Serializers", as suggested by Stephan.
