Java Serialization / Deserialization of an ArrayList works only on first program execution

To fix this issue That's exactly that, nothing is overwritten, since you explicitely chose to append rather than overwrite when writing to the file:
new FileOutputStream(FILE_NAME, true);

Hazelcast Java Serialization/Deserialization ArrayList Pitfall

should help you out I am not pretending, but after a lost day, i finally came up with a solution which workaround this. I cannot say if it is a feature or just a problem to report.
Anyway in Hazelcast if you put in an IMap a value as ArrayList thus will be Serialized Entry By Entry. Which means if we have 100 entries of the same instance A which is 6K we will have 600K with Hazelcast. Here a short RAW code which prove my answer.
public void start() throws Exception {

    HazelcastInstance client = produceHazelcastClient();

    Data data = new Data();

    ArrayList<Data> datas = new ArrayList<>();

    IntStream.range(0, 1000).forEach(i -> {


    client.getMap("data").put("LEO", datas);

    Object redeserialized = client.getMap("data").get("LEO");



public void wirteFile(Object value, String key, String fileName) {
    try {
        Files.write(Paths.get("./" + fileName + "_" + key), SerializationUtils.serialize(((ArrayList) value)));
    } catch (IOException e) {
