SPRING KAFKA BLEEDS CI TIMEOUTS AS PULSAR EYES COMMERCIAL BUILD PARITY

By RepoJournal · Filed · About Spring

Spring Kafka is drowning in timing flakes across five test suites, all fixed this morning with aggressive timeout increases to handle slow CI machines.

Five commits landed overnight to spring-kafka targeting the same root cause: consumer rebalance and producer metadata fetch operations are punching past their latch windows on loaded CI machines [1][2][3][4][5]. Soby Chacko increased timeouts from 10 to 30 seconds across ObservationIntegrationTests, ReplyingKafkaTemplateTests, PartitionResolverTests, and DeliveryHeaderTests, with all fixes auto-cherry-picking to 4.1.x and 4.0.x branches. Over in spring-pulsar, the team aligned Gradle and CI workflows with the commercial build [6][7], conditionally applying enterprise Artifactory repositories when the COMMERCIAL environment variable fires, keeping the OSS build inert. Spring-security wrapped four dependency bumps: js-yaml hit a security fix removing quadratic complexity from duplicate key detection [8], brace-expansion advanced from 1.1.11 to 1.1.18 [9], actions/setup-java refreshed to 5.7.0 [10], and the antora doc extensions bumped to 1.14.13 [11].
