-------------------------------------
With the new debug infos from FLINK-10655, we finally have some useful

Suppressed: java.lang.ClassNotFoundException: Could not deserialize 3th

indicates that the argument type is not part of the system class loader.

> Key: FLINK-10419
> URL: https://issues.apache.org/jira/browse/FLINK-10419
> Project: Flink
> Issue Type: Bug
> Components: Distributed Coordination, State Backends, Checkpointing
> Affects Versions: 1.5.0, 1.5.1, 1.5.2, 1.5.3, 1.5.4, 1.6.0, 1.6.1, 1.7.0
> Reporter: Nico Kruber
> Assignee: Nico Kruber
> Priority: Major
>
> It seems that somewhere in the operator's failure handling, we hand a
> user-code exception to the checkpoint coordinator via Java serialization but
> it will then fail during the de-serialization because the class is not
> available. This will result in the following error shadowing the real one:
