Review comment:
This serializer class previously did not have a `serialVersionUID` defined.
Need to explicitly set it to what it was before, because I guess the serial
version UID would have changed when adding the new constructors.
OTOH, there seems to be missing a migration test for this serializer,
because that would have caught this problem.
