Question

我试图改变一个类中的方法，这是有效的，但我想调用我的代码，然后用我的参数调用原始方法，这是不行的，每当我尝试这样做的时候我得到ArrayIndexOutOfBoundsException。我不知道是什么导致了它，我无法找到其他任何人。我不确定下面的代码是否正确：

        MethodNode copy = new MethodNode();
        copy.desc = method.desc;
        copy.attrs = method.attrs;
        copy.access = method.access;
        copy.exceptions = method.exceptions;
        copy.annotationDefault = method.annotationDefault;
        copy.invisibleAnnotations = method.invisibleAnnotations;
        copy.instructions.add(method.instructions);
        copy.signature = method.signature;
        copy.name = method.name + "_orig";
        originalMethod = copy;
        classNode.methods.add(copy);

完全例外：

创建方法的副本并在Java ASM中调用它
