https://github.com/apache/pulsar/pull/12729 shows the `ConcurrentOpenHashMap` allows null values. It adds a `removeNullValue` public method to handle the null values. This is very error-prone. Here is an example: ```java final var map = new ConcurrentHashMap<String, String>(); map.computeIfAbsent("A", __ -> null); System.out.println(map.size()); final var map2 = new ConcurrentOpenHashMap<String, String>(); map2.computeIfAbsent("A", __ -> null); System.out.println(map2.size()); ``` Outputs: ``` 0 1 ``` -- This is an automated message from the Apache Git Service.
