GraalVM test

A test case to compare the peformance of the Java version vs a native version of some code I was using in a different project where we noticed big performance differences. Related to issue #5968 at the Graal project.

Prerequisites

Running under an "x64 Native Tools Command Prompt" and having GraalVM CE 22.3.1 installed at GRAAL_HOME, you can perform the test with the commands below

Package .jar and create native version

set JAVA_HOME=%GRAAL_HOME%
mvn -Pnative native:compile

Run both versions

cd target

Java version

%GRAAL_HOME%\bin\java -jar graalvm-test-0.0.1-SNAPSHOT.jar

Native version
