Java Apache POI换行符随机插入到生成的页面？

Question

我正在从事一个有趣的项目，该项目可以处理创建我的自定义信头纸的过程。我正在使用Apache POI处理Word文档。我计划在完成使用AWT添加GUI并允许通过其自定义的基本框架后，对其进行扩展，这说明了如何在代码中进行设置。尝试格式化标题时，我得到了一些非常奇怪的结果，看来Apache POI会在想要的位置插入换行符？我想我不太了解。

CreateDocument.java

awk -F\' '/atop/ {print $2}' b.txt 

很简单吧？我希望得到以下结果：

}

但困惑的是：

我想念一些东西，愚蠢的东西还是两者兼而有之？
