> This is because System.getEnv() returns a java.util.Collections$UnmodifiableMap which isn't supposed to be changed during runtime code. To workaround this, normally we need to use reflection way to make a private field in java.util.Collections$UnmodifiableMap accessible.
> But this is kind of against the encapsulation(Strongly Encapsulate JDK Internals ) rule of java Modules since JDK9. Before JDK17, it is it possible to access internal APIs via the --illegal-access command line option which is enabled by default. However, since JDK17 this --illegal-access is removed and we need to either explicitly use --add-opens modules to enable deep reflection for JDK internal code, or we need to get rid of the way to use JDK Internals
