@zeitlinger It seems related to the Spring code, not the OTel Starter code (to check).

In this case, the following code in the RuntimeHints class solves the issue:

    hints
        .reflection()
        .registerType(
            TypeReference.of("org.springframework.data.mongodb.core.aggregation.AggregationOperation"),
            hint -> {
              hint.withMembers(MemberCategory.INVOKE_DECLARED_CONSTRUCTORS, MemberCategory.INVOKE_DECLARED_METHODS);
            });

@zeitlinger I confirm that the GraalVM native issue is related to the Spring code, not the OpenTelemetry code. I have pushed a fix on your branch.
