>                 URL: https://issues.apache.org/jira/browse/IGNITE-16640
>             Project: Ignite
>          Issue Type: Bug
>          Components: compute, persistence
>    Affects Versions: 2.12
>            Reporter: Roman Puchkovskiy
>            Assignee: Roman Puchkovskiy
>            Priority: Major
>              Labels: ise.lts
>             Fix For: 2.13

>          Time Spent: 20m
>  Remaining Estimate: 0h

> The problematic scenario:
>  # Enable p2p class-loading in the cluster
>  # Create a cache
>  # From a client, obtain a dataStreamer on that cache and set a receiver() which class is only present on the client (so that it is forced to be loaded using p2p)
>  # The receiver class, during its operation (inside its receive() method), should initiate loading of another class only present on the client
>  # If at the moment, when an attempt is made to load the class mentioned in item 4, the client is not available anymore, a class-loading exception happens on the server node, which is manifested as a NoClassDefFoundError, which is caught and processed by its Failure Handler. If the handler is 'stop-or-halt', the node is stopped.
> So the scenario might cause a node failure, even though the original problem is local and transient. We should distinguish between p2p class load errors (which are non-critical) and non-p2p class load errors (which are critical).
