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

             Summary: AfterMatchSkipStrategy not working on notFollowedBy ended pattern
                 Key: FLINK-31042
                 URL: https://issues.apache.org/jira/browse/FLINK-31042
             Project: Flink
          Issue Type: Bug
          Components: Library / CEP
    Affects Versions: 1.16.1, 1.15.3, 1.17.0

             Fix For: 1.17.0, 1.15.4, 1.16.2, 1.18.0


Pattern: begin("A", SkipToNext()).oneOrMore().allowCombinations().followedBy("C").notFollowedBy("B").within(Time.milliseconds(10L))

Sequence: <a1, 1L> <a2, 2L> <a3, 3L> <c1, 4L> will produce

[a1, a2, a3, c1]

[a1, a2, c1]

[a1, c1]

[a2, a3, c1]

[a2, c1]

[a3, c1]

Using SkipPastLastEvent() also produce the same result.
