Conversation
…Tel is active Skip registration of SentryKafkaProducerBeanPostProcessor and SentryKafkaConsumerBeanPostProcessor when a Sentry OpenTelemetry integration (agent or agentless) is on the classpath. OpenTelemetry provides its own Kafka instrumentation, so Sentry's would create duplicate spans.
Add auto.queue.spring_jakarta.kafka.producer and auto.queue.spring_jakarta.kafka.consumer to the ignored span origins when running with OTel agent or agentless-spring. Prevents duplicate spans when both Sentry and OTel Kafka instrumentation are active.

📜 Description
Disable Sentry's Kafka queue instrumentation when a Sentry OpenTelemetry integration (agent or agentless) is active, to avoid duplicate spans:
@ConditionalOnMissingClass("io.sentry.opentelemetry.SentryAutoConfigurationCustomizerProvider")toSentryKafkaQueueConfigurationso the Kafka bean post processors are not registered when OTel is present.auto.queue.spring_jakarta.kafka.producerandauto.queue.spring_jakarta.kafka.consumertoSpanUtils.ignoredSpanOriginsForOpenTelemetry()for AGENT and AGENTLESS_SPRING modes as a second layer of protection.💡 Motivation and Context
OpenTelemetry provides its own Kafka instrumentation. When both Sentry and OTel instrument Kafka, duplicate spans are created. This disables the Sentry side when OTel handles it.
💚 How did you test it?
Unit tests in
SentryKafkaAutoConfigurationTest— added a test verifying beans are not registered when OTel is present, and updated existing tests to useFilteredClassLoaderto simulate OTel absence.📝 Checklist
