By compiling before the program executes, the AOT compiler must be conservative about classes, fields, and methods referenced by the code it compiles.

由于在程序执行前进行编译，AOT编译器必须谨慎对待它所编译的代码所引用的类、字段和方法。

Increasingly, objects are "dynamic" in the sense that their structure and behavior is not captured by a static type, or at least not one that the compiler knows about when compiling your program.

对象的意义变得越来越“动态”，它们的结构和行为无法通过静态类型来捕获，或者至少编译器在编译程序时无法得知对象的结构和行为。
