内部错误！错误编码：ui-08

版本：5.2.7
之前做过一个功能，是在上传附件时拦截servletRequest请求对文件的inputstream进行加密包装后再继续上传，目前已完成。http://bbs.wex5.com/forum.php?mod=viewthread&tid=113449
现在要做的是在附件组件点击下载的时候对加密过的文件先进行解密然后再下载，但是下载部分的代码被平台封装在ui-core.jar里了，无奈只好对com.justep.ui.system.service.doc.DocUtils.class尝试反编译进行修改，反编译后在myeclipse的IDE中编译正常（无报错等信息），但是重新把编译过的DocUtils.class放回ui-core.jar后，启动服务报错：内部错误！错误编码：ui-08，请问下应该怎么解决，因为需求好像无法绕开修改下载部分源码的问题了。
反编译修改代码如下：

平台的这个jar中文件不能修改，必须用平台默认的带的，里面有安全的校验

那如果不修改这个jar，我可以在其他地方获取到下载文件的流吗？

还可以跟上传的时候一样的实现啊，自己定义个.j，在.j中处理，可以参考excel导出的.j的实现
/UI/system/components/excel/export/download.j
