java - 当一个项目配置JDK时，会加载JDK中的哪个.jar文件？

Question

在我的 IntelliJ IDEA 中，当配置 JDK 并为一个项目选择 JDK home 时，将加载下面的 classpath/jar 文件。

但据我所知，JDK 主路径中有一些 jar 文件未加载，

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。

如何生效？我可以选择特殊设计的JDK并在其他地方加载一些jar吗？我在哪里可以更改加载规则，在IDEA中还是在JDK源代码中？
