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

             Summary: Unexpected behavior using greedy on looping pattern with 
notFollowedBy at end
                 Key: FLINK-31044
                 URL: https://issues.apache.org/jira/browse/FLINK-31044
             Project: Flink
          Issue Type: Bug
          Components: Library / CEP
    Affects Versions: 1.16.1, 1.15.3, 1.17.0
            Reporter: Juntao Hu
             Fix For: 1.17.0, 1.15.4, 1.16.2, 1.18.0


Pattern without greedy: begin("A" , 
SKIP_PAST_LAST).oneOrMore().consecutive().notFollowedBy("B").within(Time.milliseconds(10))

Pattern with greedy: begin("A", 
SKIP_PAST_LAST).oneOrMore().consecutive().greedy().notFollowedBy("B").within(Time.milliseconds(10))

For sequence: <a1, 1L> <a2, 2L> <a3, 3L>, after FLINK-31040 and FLINK-31042 
fixed, both of the patterns should produce [a1, a2, a3] , when currently the 
pattern with greedy option makes no output.
