Problems using TransmittableThreadLocal in NameMapper

[yixiaco]

NameMapper cannot get the value in InheritableThreadLocal. Even if I use TransmittableThreadLocal and set setExecutor and setNettyExecutor, I cannot get the variable in the child thread in unmap.

public class KeyPrefixHandler implements NameMapper {
  public String map(String name) { return name; }
  public String unmap(String name) {
    // Neither in the main thread nor in the child thread
    System.out.println(TEMP.get()); // null
    return name;
  }
}

@AutoConfiguration
public class RedisConfig {
  @Bean
  public RedissonAutoConfigurationCustomizer redissonCustomizer(RedissonProperties redissonProperties) {
    return config -> {
      config.useSingleServer().setNameMapper(new KeyPrefixHandler(redissonProperties.getKeyPrefix()))
      int threads = Runtime.getRuntime().availableProcessors() * 2;
      if (config.getThreads() != 0) {
          threads = config.getThreads();
      }
      config.setExecutor(TtlExecutors.getTtlExecutorService(Executors.newFixedThreadPool(threads, new DefaultThreadFactory("redisson"))));
      config.setNettyExecutor(TtlExecutors.getTtlExecutor(new ThreadPerTaskExecutor(new DefaultThreadFactory("redisson-netty"))));
      // ...
    }
  }
}

public class Test {
  private static final ThreadLocal<Boolean> TEMP = new TransmittableThreadLocal<>();

  public static void main(String[] args) {
    TEMP.set(true);
    Stream<String> stream = redissonClient.getKeys().getKeysStreamByPattern("test:*");
    stream.collect(Collectors.toList());
    TEMP.remove();
  }
}
