推荐答案

简单的答案是这样的：一些代码试图调用一个声明为 abstract 的方法。抽象方法没有主体，无法执行。由于您提供的信息很少，因此我无法详细说明如何发生这种情况，因为编译器通常会解决这个问题 - 如此处所述，这意味着该类必须在运行时更改。

The simple answer is this: some code is trying to call a method which is declared abstract. Abstract methods have no body and cannot be executed. Since you have provided so little information I can't really elaborate more on how this can happen since the compiler usually catches this problem - as described here, this means the class must have changed at runtime.
