Dave Marion commented on ACCUMULO-4062:
---------------------------------------

{code}org.apache.accumulo.core.data.Mutation#hashCode{code} in master looks 
like this for me:

{code}
  @Override
  public int hashCode() {
    return serializedSnapshot().hashCode();
  }
{code}

what code are you looking at?
