Could you also add a smoke test for this similarly to

then: "service name is autodetected"
def serviceName = findResourceAttribute(traces, "service.name")
.map { it.stringValue }
.findAny()
serviceName.isPresent()
serviceName.get() == "otel-spring-test-app"
You'll also have to update the tag in
"ghcr.io/open-telemetry/opentelemetry-java-instrumentation/smoke-test-spring-boot:jdk$jdk-20230321.4484174638"
to 20230920.6251727205 (if I didn't mess anything up that version should contain the build-info.properties)

InputStream openClasspathResource(String filename, String location) {
String path = location + "/" + filename;
return classLoader.getResourceAsStream(path);
}

Now that the SystemHelper is used in two classes, WDYT about making it a top-level class?

I think putting "META-INF" first makes more sense, since it's a directory that contains the build info file

Suggested change
try (InputStream in = system.openClasspathResource("build-info.properties", "META-INF")) {
try (InputStream in = system.openClasspathResource("META-INF", "build-info.properties")) {
