Apache flink Can'；在对有状态函数使用数据流集成时，无法还原保存点

我的flink应用程序正在使用带有的有状态函数，每次尝试从保存点还原时，我在

datstream应用程序和stateful函数应用程序似乎都是单独工作的，但当它们使用statefun 2.2版中的新集成进行组合时，从保存点恢复将停止工作

我想知道这是否与以下事实有关：当有状态函数仅支持处理时间语义时，我正在为datastream应用程序使用
env.setStreamTimeCharacteristic（TimeCharacteristic.EventTime）
，因为我认为这是Flink中的一个bug：
