> {{RemoteRpcInvocation}} tries to give a more detailed {{ClassNotFoundException}} if the method type/argument deserialization fails. However, it turns out, once {{ObjectInputStream}} has received a {{ClassNotFoundException}}, it will not overwrite this anymore and we can therefore not provide a more detailed {{ClassNotFoundException}}.
> Instead, the least invasive solution would be to add a suppressed {{ClassNotFoundException}} to the existing one. While at it, we could also add more details, i.e. the successfully deserialized types and arguments.
