Java scala类spark submit的反序列化问题

我正在尝试一个scala和java相结合的项目，我有一个scala类，它的缩写结构如下

 case class Dl(name:String, length:Int) extends Serializable 

 class DlStruct private(xs:List[Dl]) extends Serializable {
    def this()= this(Nil)

    private def +=(dl:DataLayout): RowSchema =
      new RowSchema(xs :+ dl)

    def appendDl(fieldName:String, fieldLength:Int):DlStruct=
      this += Dl(fieldName,fieldLength)

 }

上面的类是从java对象调用的，用于填充DlStruct，完成后，我将把类文件写成序列化文件

当我再次反序列化文件并将其转换回object时，当我使用IntelliJ时，它工作得非常好，但如果我尝试从spark submit运行相同的代码，则会抛出以下错误：-

java.lang.ClassCastException: cannot assign instance of scala.collection.immutable.List$SerializationProxy to field somepackage.DlStruct.xs of type scala.collection.immutable.List in instance of somepackage.DlStruct.xs

对于公共java对象的反序列化也没有问题

用于反序列化的代码段

 File file = new File(serializedFilePath);
 FileInputStream fin = new FileInputStream(file);
 ObjectInputStream in = new ObjectInputStream(fin);

 infoHolder = (ObjectCarrier) in.readObject(); // <- this line gives error if it has scala object, else runs smoothly

 in.close();
 fileIn.close();

File File=新文件（序列化文件路径）；
FileInputStream fin=新的FileInputStream（文件）；
ObjectInputStream in=新的ObjectInputStream（fin）；
infoHolder=（ObjectCarrier）在.readObject（）中；// 我必须将scala类转换为java，才能让它最终在spark submit中工作，我希望有人能找到更好的答案。
您使用的是哪种spark和scala版本？它们是否与spark submit使用的版本相同？顺便说一下，case类在默认情况下是可序列化的。在我的POM中指定的版本是2.12.8 2.4.4，哪个JDK版本？基于stacktrace，它看起来相当新。并不是所有最新的JDK版本都能保证与所有不是最新的scala版本（OpenJDK1.8.0òu）一起工作，但我很确定，提供stacktrace的JVM应该比1.8版本更新。
