   Thanks @leventov , I want to clarify that even if `segment` is removed, the reference to `segment` is still there. So where do you think, it can cause a NPE ?  Though a null check for `dataSourceSegments` can be added before `SegmentMetadataHolder holder = dataSourceSegments.get(segment);`. Does that address your concern ?
