Hi team,

After upgrading com.google.cloud:google-cloud-recaptchaenterprise from 3.79.0 to 3.80.0 we get a runtime failure:

java.lang.NoClassDefFoundError: com/google/protobuf/RuntimeVersion$RuntimeDomain
at com.google.recaptchaenterprise.v1.CreateAssessmentRequest.(CreateAssessmentRequest.java:40)
at com.google.cloud.recaptchaenterprise.v1.stub.GrpcRecaptchaEnterpriseServiceStub.(GrpcRecaptchaEnterpriseServiceStub.java:93)
at com.google.cloud.recaptchaenterprise.v1.RecaptchaEnterpriseServiceClient.create(RecaptchaEnterpriseServiceClient.java:601)
...

Caused by: java.lang.ClassNotFoundException: com.google.protobuf.RuntimeVersion$RuntimeDomain

This does not happen with 3.79.0.

Environment

• Runtime: Keycloak 26.5.2 (Quarkus-based)
• At runtime, protobuf-java is provided by the container and is com.google.protobuf:protobuf-java:3.25.5
• Application code only needs to create the client and call CreateAssessment.

Question

• Is protobuf-java 3.25.5 still supported for google-cloud-recaptchaenterprise 3.80.0?
• If not, could you please document/enforce the minimum required protobuf-java version (dependency constraints / BOM alignment), since 3.79.0 worked with 3.25.5 and 3.80.0 now fails?

Thanks!
