             Summary: Update `JobGraphUtils` type to class
                 Key: FLINK-19713
                 URL: https://issues.apache.org/jira/browse/FLINK-19713
             Project: Flink
          Issue Type: Improvement
    Affects Versions: 1.11.0
            Reporter: xiaozilong


Hi, I found that the `org.apache.flink.runtime.jobgraph.JobGraphUtils` is an enumeration, but there is one static method. Why not define JobGraphUtils as a class instead of an enumeration?
