-------------------------------------

             Summary: WindowOperator logs about "re-registering state from an older Flink version" even though its not a restored window
                 Key: FLINK-5450
                 URL: https://issues.apache.org/jira/browse/FLINK-5450
             Project: Flink
          Issue Type: Bug
          Components: Windowing Operators
    Affects Versions: 1.2.0
            Reporter: Robert Metzger


While testing the RC0 of Flink 1.2, I stumbled across this log message

{code}
15:42:02,855 INFO  org.apache.flink.streaming.api.operators.AbstractStreamOperator  - WindowOperator (taskIdx=WindowOperator) re-registering state from an older Flink version.
{code}

My WindowOperator is not restored, so I find this log message a bit misleading.
