自己写的 UI 自动化框架用 excel 管理测试数据，框架启动时用 jxl 加载文件，报 StringIndexOutOfBoundsException。相关代码：

其中红框处报这个异常，如下：
ExcelData 数据文件加载失败！
java.lang.StringIndexOutOfBoundsException: String index out of range: 120
at java.lang.String.checkBounds(Unknown Source)
at java.lang.String.(Unknown Source)

at myframework.uitest.data.ExcelData.(ExcelData.java:38)
at myframework.uitest.run.Runner.run(Runner.java:57)
at TestRunner.main(TestRunner.java:45)
测试执行中出现异常！
java.lang.NullPointerException

此框架在以前的电脑上正常运行，换了电脑后遇到此问题，有人遇到过吗？？求助啊！
