序列化此对象会导致StackOverFlowError：

import java.nio.file.Path;
import java.nio.file.Paths;
public class Tmp{
    private Path path=null;
    public Tmp() {
        path=Paths.get("c:\\temp\\");
    }
}

在我看来这是一个bug！或者我做错了什么？有什么解决方法吗（希望编写一些自定义的序列化程序，将路径转换为字符串）

序列化方法为：

public static void saveTo(BatchLogging logging, Path path) throws IOException {
    Gson gson=new GsonBuilder().setPrettyPrinting().create();
    // String json = gson.toJson(logging);
    String json = gson.toJson(new Tmp());
    List<String> lines = Arrays.asList(json.split(System.lineSeparator()));
    Files.write(path, lines, StandardCharsets.UTF_8);
}
