p->next 表面上就是取 p 所指方框（本质是一块内存块）中的 next 的值。
while(p->next ！= NULL) 循环结束时，此时p的位置是尾节点的位置，但如果用于输出函数的判断条件，...

注意到那个 **ShouldBlockAccessToMember** 调用了吗?如果它返回 true,那么直接返回`nullptr`,上层就会抛 `NoSuchMethodXXX` 异常;也就触发系统的限制了。于是我们继续跟踪这个方法,这个方法的实现在java_lang_Class.cc,源码如下: ALWAYS_INLINEstaticboolShouldBlockAccessToMember(T*member,Thread*self)REQUIRES_SHARED...
