Andrei Iliev commented on LUCENENET-287:
----------------------------------------

Don't forget  to override GetHashCode., e.g 
        public override  int GetHashCode()
        {

            int h = 1;
            for (int i = 0; i< this.Count; i++)
            {
                SegmentInfo si = (this[i] as SegmentInfo) 
                h = 31 * h + (si == null ? 0 : si.GetHashCode());
            }

            return h;
        }

> SegmentInfos  is derived from ArrayList. So Equals and GetHashCode should behave as java
ArrayList (see LUCENENET-284).
> After that patch TestIndexWriterReader.TestUpdateDocument is passed.
