Spring AI is cutting unnecessary dependencies and deprecating its ChatClient customizer in a cleanup push that signals cleaner architecture ahead.

Spring AI merged four cleanup commits that remove transitive dependency bloat [1][2][3], including spring-boot-jdbc from Redis modules and redundant starter dependencies that were already inherited. These removals ship alongside a ChatClient customizer deprecation [4] that introduces ChatClientBuilderCustomizer to replace it, updating the entire builder pattern in one sweep. Over in Spring Boot, a critical file descriptor leak in InspectingOutputStream went unpatched until now [5], with the stream failing to close its underlying FileOutputStream delegate when content exceeds the 4KB memory limit, leaving handles dangling. The same session also fixed an RSocket-specific null pointer exception in SSL bundle lookups [6] that was already corrected in the shared customizer but missed in RSocket's modularized copy. Rounding out the day: Jackson bumped to 3.1.4 across both Security and Session [7][8][9], mockk updated to 1.14.11 with matcher improvements [10], and documentation corrections landed for Gradle module replacement references [11][12][13].

Action items

→ Upgrade Spring Boot before next deploy to patch FileOutputStream leak spring-projects/spring-boot [immediate]
→ Review Spring AI ChatClient customizer usage, plan migration to ChatClientBuilderCustomizer spring-projects/spring-ai [plan]
→ Bump Jackson to 3.1.4 across Security and Session projects spring-projects/spring-security [plan]
→ Monitor RSocket SSL bundle handling in next Spring Boot release spring-projects/spring-boot [monitor]
