Observed that SequencedMap:firstEntry() throws NullPointerEx when the map entry has null key or null value. Example : the following code snippet throws NPEx. ======== ( When key is null ) SequencedMap<String, String> sequencedMap = new LinkedHashMap<>(); sequencedMap.put(null, "v1"); sequencedMap.firstEntry(); ======== (When value is null ) SequencedMap<String, String> sequencedMap = new LinkedHashMap<>(); sequencedMap.put("k", null); sequencedMap.firstEntry(); =====
