### Search before asking - [x] I had searched in the [issues](https://github.com/apache/fury/issues) and found no similar issues. ### Version 0.10.2 (already cherry picked #2135) ### Component(s) Java ### Minimal reproduce step ## Reproduction requirements 1. Serializing a nested map (directly serializing a map works) 2. The map type is anything but Map<String, String> 3. The map contains both null and non-null values 4. Codegen is enabled ## Reproduction code ```java public class Pojo { public Map<String,List<Long>> stringInt64ListMap; } ``` ```java Fury fury = Fury.builder().withLanguage(Language.JAVA).withCodegen(true).build(); fury.register(Pojo.class); Pojo pojo = new Pojo(); pojo.stringInt64ListMap = new HashMap<String, List<Long>>(); pojo.stringInt64ListMap.put("a", Arrays.asList(100L, 200L, 300L)); pojo.stringInt64ListMap.put("b", null); fury.serialize(pojo); ``` ### What did you expect to see?
