2. generate config with Tracing Agent: "graalvm-ce-java17-22.3.0-dev\bin\java -agentlib:native-image-agent=config-merge-dir=config -cp lib/* Test --verbose --initialize-at-run-time --enable-all-security-services --no-fallback"
3. build the native image: "graalvm-ce-java17-22.3.0-dev\bin\native-image --native-image-info --verbose -H:ConfigurationFileDirectories=config -H:+ReportExceptionStackTraces --enable-url-protocols=https,http -cp moduleslib/* -jar lib/test.jar"
4. run the executable: " \graalvm-poc>test"
