Java 处理文件的小程序在本地工作，但在网站中失败

这几天来我一直在讨论这个问题。我已经完成了我的谷歌搜索，我希望我能在这里找到一个比我更有经验的人（不难找到哈哈）来破解我的问题

场景：我开发了一个实现Swing GUI的Java小程序。后台工作：小程序从一个大的“电话簿”excel文件（.csv）中收集记录，并将其存储在地图数据结构中。电话簿包含大约106000条记录，在34586条记录中，我得到了一个我无法理解的ArrayIndexOutofBounds异常只有在我的个人网站上运行小程序时才会发生异常。在我的IDE（NetBeans）中测试并在本地计算机上运行.html文件（包含小程序的文件）时，小程序运行得非常好，没有错误。在我的网站上运行时引发的输出和异常如下（我剪切了大部分记录以节省空间）：

Java控制台

如您所见，在34586条记录（从Patsy，Hart开始）上，它在她的地址中间输出。完整记录如下：Patsy，Hart，661 East 11th St.Apt.195，孟菲斯，田纳西州，38168555-555-5555

下面是受异常逻辑影响最大的代码部分

HTML文件中的对象标记

小程序无法运行。找不到Java插件。
