当一个项目使用JDK进行配置时，JDK中的哪个.jar文件会被加载？

Question

在我的IntelliJ想法中，当配置JDK并为一个项目选择JDK home时，将加载下面的类路径/jar文件。

但据我所知，JDK主路径中有一些jar文件没有加载，

例如，同一路径下的此文件尚未加载:/Library/Java/JavaVirtualMachines/jdk1.8.0_161.jdk/Contents/Home/jre/lib/security/policy/limited/US_export_policy.jar.

这是如何产生效果的？我可以选择特殊设计的JDK并在其他地方加载一些jar吗？我可以在哪里更改加载规则，在IDEA中还是在JDK源代码中？
