Executing insinde the JVM as a jar

1. Build the fat JAR: ./gradlew jar

2. Execute the default Jar:

    $ java -jar build/libs/aot-reflection-test.jar
    Hello, world!
   

3. Pass configuration by the environment:

    $ GREETING="What's up" NAME="gang" java -jar build/libs/aot-reflection-test.jar
    What's up, gang!
   

Allow reflection with GraalVM AOT

Aot-test without reflection:

    $ ./gradlew jar
    $ native-image --no-fallback -H:ReflectionConfigurationFiles=reflectconfig.json\
            -jar build/libs/aot-reflection-test.jar aot-test
    $ GREETING="What's up" NAME="gang" ./aot-test
    What's up, gang!

Limitations: can't write in final variables neither static:

public static final String GREETING = KA.def("Hello");

nor simple final variables with the config: { "name" : "name", "allowWrite" : true }
