@zhangminglei I don't think this properly solves the issue. The problem is
that we need a migration path from the Java serialization shortcut, and not
simply replace it. Otherwise we would be breaking state compatibility with
older versions.
So, in `initializeState` we should try to read the state using the Java
serialization shortcut, and in `snapshotState` write it using a new proper
state accessing `ListState`.
