@haoyuan-l I have created a unit test for the XML serliazation.
Unfortunately the serialization doesn't behave nicely. I have not been able to configure it to handle the inheritance correctly, and it is getting confused when trying to de-serialize

Are there any errors when you deserialized the tiers list?

Yes, its broken at the moment. There will be some errors, but since these are on worker threads, they only kill those threads. The problem is that the deserializaton itself fails, for example because ctors are missing.
This kind of serialization needs special handling for everything which is not a plain 'java bean' property

@haoyuan-l I can make more progress using JSON.... now it is complaining that the ctor doesn't exist.
The classes need to handle the deserialization....

So currently we can serialize the tier list to a JSON file but broke when we deserialized the file. Can you share a snapshot of the JSON file? And also I found a post about deserializing the Arraylist:

Not sure... It seems we deserialized to ArrayList without any generic type.
(e.g. List tiers = (List)m_xmlMapper.readValue(fr, ArrayList.class))
