Description

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

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

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