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

             Summary: SharedBuffer#hashCode() uses multiplier in wrong way
                 Key: FLINK-6624
                 URL: https://issues.apache.org/jira/browse/FLINK-6624
             Project: Flink
          Issue Type: Bug
            Reporter: Ted Yu
            Priority: Minor


In SharedBuffer.java:
{code}
    public int hashCode() {
      return (int) (31 * (timestamp ^ timestamp >>> 32) + 31 * value.hashCode()) + counter;
{code}
Multiplier of 31 is applied to both (timestamp ^ timestamp >>> 32) and value.hashCode().
The following is probably the right expression:
{code}
      return (int) 31 * (31 * (timestamp ^ timestamp >>> 32) + value.hashCode()) + counter;
{code}
