[java10] An illegal reflective access operation

[dfa1]

First of all thanks for this nice and well written library.

Running a test suite using system-rules 1.18 in JDK10 in macosx outputs:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.junit.contrib.java.lang.system.EnvironmentVariables (file:/Users/dfa/.m2/repository/com/github/stefanbirkner/system-rules/1.18.0/system-rules-1.18.0.jar) to field java.util.Collections$UnmodifiableMap.m
WARNING: Please consider reporting this to the maintainers of org.junit.contrib.java.lang.system.EnvironmentVariables
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

Thanks for the information but AFAIK there is no way to modify environment variables without using this illegal reflective access.

I didn't noticed that getenv() is a view on the actual system env.

@stefanbirkner I upgraded to jdk-17 and now I am blocked by this since I am getting this error
