[jira] [Created] (FLINK-3682) CEP operator does not set the processing timestamp correctly

Till Rohrmann created FLINK-3682:
------------------------------------

             Summary: CEP operator does not set the processing timestamp correctly
                 Key: FLINK-3682
                 URL: https://issues.apache.org/jira/browse/FLINK-3682
             Project: Flink
          Issue Type: Bug
          Components: CEP
    Affects Versions: 1.0.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
             Fix For: 1.1.0, 1.0.1


In the wake of reworking the timestamp assignment where the processing timestamp has to be set now by the {{StreamOperator}}, the CEP operators have not been adapted. This causes that the timestamp value assigned to the {{StreamRecord}} is used. In case of processing time this is {{Long.MIN_VALUE}}. In combination with a CEP time window, this can lead to an underflow in the NFA where the window time is subtracted from the current timestamp value.
