That's a valid point! However, this might come down to the question of whether it is worth having dependency on graal-sdk in this repo? If we use the latest version (22.1.0) then we'll see the following incompatibility:
bad class file: /home/runner/.m2/repository/org/graalvm/sdk/graal-sdk/22.1.0/graal-sdk-22.1.0.jar(org/graalvm/nativeimage/ImageInfo.class)
Error: class file has wrong version 55.0, should be 52.0
Error: Please remove or make sure it appears in the correct subdirectory of the classpath.
Error: -> [Help 1]
In which case, we may need to do something similar to googleapis/gax-java#1671. This could still pose a slight risk since we still target Java 7. But open to hearing about what you think!

I'm fine with either. @suztomo what do you think? Is it worth it to bring the whole setup for compiling with 11 and testing on 7 in this case?

This contributes towards removing the use of the SVM dependency for native image compilation. This code makes use of the org.graalvm.nativeimage.imagecode system property instead of
Substitutionsto set the Java version at image runtime. For reference: https://www.graalvm.org/sdk/javadoc/index.html?constant-values.htmlSee reproducer: https://github.com/mpeddada1/avoid-substitutions
