Encountered an IllegalStateException while traversing with Flat3Map.entrySet() {code:java} //代码示例 public void testEntrySet() { final Flat3Map<Integer, String> map = new Flat3Map<>(); map.put(1, "A"); map.put(2, "B"); map.put(3, "C"); Iterator<Map.Entry<Integer, String>> it = map.entrySet().iterator(); Map.Entry<Integer, String> mapEntry1 = it.next(); Map.Entry<Integer, String> mapEntry2 = it.next(); Map.Entry<Integer, String> mapEntry3 = it.next(); it.remove(); assertEquals(2, map.size()); } {code} Using the above code will generate an IllegalStateException. The reason for this problem is that there is a problem with the EntryIterator.remove() method in the Flat3Map java class. -- This message was sent by Atlassian Jira (v8.3.4#803005)
