-------------------------------
PS:
org.apache.flink.streaming.api.windowing.windows.TimeWindow.Serializer
org.apache.flink.streaming.api.windowing.windows.GlobalWindow.Serializer
org.apache.flink.table.runtime.operators.window.TimeWindow.Serializer
org.apache.flink.table.runtime.operators.window.CountWindow.Serializer
These four Serializers seem all to have this issue which return 0 length.
Then what does getLength() method for? It seems whether the length is right or
wrong matters nothing.
> GlobalWindow.Serializer#getLength() provides a wrong length.
