我是apache-poi的问题，使用：
poi-3.7.jar
POI-OOXML-3.7.jar
当我尝试安装新的工作簿时：
XSSFWorkbook workbook = new XSSFWorkbook(someInputStream());
应用程序抛出此异常：
java.lang.NoClassDefFoundError cannot be cast to java.lang.Exception
完成堆栈跟踪：
java.lang.ClassCastException: java.lang.NoClassDefFoundError cannot be cast to java.lang.Exception
