想编写一个映射的 Spliterator 类：
public abstract class MappedSpliterator<T, E> implements Spliterator<E> {}
经过尝试，即使是如上所示的空类，也会导致 javac 报错 StackOverflowError。
这可能是什么原因造成的呢？
根据评论的提醒，我新建了工程单独创建该类，竟然没报错。
而我将该类加入原工程，仍然报错，现添加描述希望能够提供更多信息。
在 IDEA 里 build 报错截图：
使用 Maven 编译并把异常输出：

截取文本的最后是重复的栈“循环节”，再往前均为该循环节：

现在还是很困惑，希望得到指教。
