关于ConcurrentHashMap 迭代器遍历的问题

< img width="850" height="194" alt="Image" src="https://GitHub.com/user-attachments/assets/ed59cdb4-922b-4bea-85b7-3d96e25a3edb" /> It is incorrect to classify ConcurrentHashMap as fail-safe, because ConcurrentHashMap is weakly consistent during traversal, and it does not clone the original data during traversal. Therefore, there may be data inconsistency problems in a multi-threaded scenario, and no exceptions will be thrown.
