Nico Kruber updated FLINK-10655:
--------------------------------
Description:
{{RemoteRpcInvocation}} tries to give a more details {{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.
