Full ack, but the problem is not just RocksDB, but also savepoints, which
reference a user class in the state descriptor, including FS snapshots. So if
you configure a file backend and use folding or reducing state, you run into
the issue as well.
What about the following: make it optional and fail with a proper error
message in case of a missing user code class. SubtaskState (previously
StateForTask), which fails to dispose the state snapshots currently only logs
the Exception. We can change this to rethrow and then we give a proper error
message on failed savepoint disposal.
