fix: use JVM-based Kafka test image instead of kafka-native - #28
Merged
Conversation
The GraalVM native-image Kafka container (apache/kafka-native) crashes intermittently in CI with a SIGSEGV during class initialization (a race in getpwuid across the Substrate VM's startup threads), causing testcontainers to time out waiting for the broker to become ready. This blocked dependabot PRs #26 and #27 even though their actual dependency changes were unrelated to the failure. Switching to the standard JVM-based apache/kafka image avoids the native-image startup path entirely.
