java.lang.Error：Structure.getFieldOrder（）返回名称与声明的字段名称不匹配（但它们确实如此）

Question

我正在尝试模糊一些代码，主类中的一个方法引用了这个Shell32X.java类。主类中的方法（此处未显示）应该调用另一个具有管理清单的程序，以便显示UAC提示。当我对主jar进行模糊处理时，我得到一个错误，指向这个引用的类（下面）：
java.lang.Error: Structure.getFieldOrder() on class MyMainClass returns names ([cbSize, dwHotKey, fMask, hInstApp, hKeyClass, hMonitor, hProcess, hwnd, lpClass, lpDirectory, lpFile, lpIDList, lpParameters, lpVerb, nShow]) which don't match declared field names
但是，尽管我可以说它们确实匹配。那么问题是什么？
