社区各位大佬，我遇到了一个Flink版本升级后，savepoint不会正确恢复问题。
版本从1.9.3 升级到1.11.0或1.11.3.
连接器使用的pulsar的连接器。在Source的checkpoint数据结构如下
oldUnionOffsetStates = stateStore.getUnionListState(
new ListStateDescriptor<>(
OFFSETS_STATE_NAME,
TypeInformation.of(new TypeHint<Tuple2<String, MessageId>>() {
})));
oldUnionSubscriptionNameStates =
stateStore.getUnionListState(
new ListStateDescriptor<>(
OFFSETS_STATE_NAME + "_subName",
TypeInformation.of(new TypeHint<String>() {
})));
我在本地通过bin/flink savepoint 命令保存下1.9.3的state，然后停止flink
1.9.3的集群，启动1.11.3的flink集群，使用bin/flink run -s 参数恢复任务。
任务在启动后，会遇到下面的错误
