想编写一个映射的Spliterator类：

public abstract class MappedSpliterator implements Spliterator {}

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。
