In order to avoid the same problem, do we need to improve
`ConcurrentOpenHashMap`?
In `ConcurrentHashMap`, The same operation throws an exception, which makes
it easier to spot the problem.
For example below:
```
Map<String, String> map = new ConcurrentHashMap<>();
map.computeIfAbsent("test", (key) -> {
map.remove("test");
return "ok";
});
```
It will throw `java.lang.IllegalStateException: Recursive update`
