Aug 1, 2025August 2025 (2025-08) was focused on lifecycle control, proxying improvements, transactional enhancements, and ecosystem modernization in spring-framework. The work delivered more reliable runtime behavior, clearer proxy semantics, and stronger alignment with downstream services, while upgrading core dependencies to modern runtimes and libraries. This reduces operational risk, shortens startup/shutdown cycles, and enables more predictable long-running service patterns across Spring-based applications. Key features delivered: - ConfigurableApplicationContext.pause() and SmartLifecycle.isPauseable(): new lifecycle controls to pause/resume long-running beans safely without destabilizing active work. - StatelessSession transactional support: parity with regular Session for transactional guarantees on StatelessSession usage. - BEFORE_COMMIT listener propagation: allow any @Transactional propagation for listeners in the BEFORE_COMMIT phase, enabling richer transaction-scoped event handling. - Proxying improvements: default ProxyConfig bean, bean-specific proxy type annotation @Proxyable, plus documentation clarifying defaults and usage, improving proxy predictability and per-bean customization. - Performance and reliability enhancements: NIO path resolution optimization in PathEditor and early interruption for close operations (cancelRemainingTasksOnClose). - Bean resolution and lifecycle polish: caching bean type alongside primary names during singleton creation and aligning bean resolver nullability. - Retry mechanism API enhancements: expose RetryException details (getRetryCount), support maxAttempts(0), expose onRetryPolicyExhaustion, and ensure retryable proceed() behavior with invocableClone. - Dependency and library modernization: Hibernate ORM upgraded to 7.1; Reactor 2024.0.9 and Micrometer 1.14.10; Reactor 2025.0.0-M6/M2, Jetty 12.1.0.beta3; Protobuf 4.32, HtmlUnit 4.15, Mockito 5.19; Netty 4.2.4; general JDK compatibility improvements (avoid default AutoCloseable in ExecutorService on JDK 19+). Major bugs fixed: - Align task execution tracking and thread interruption on shutdown for more predictable shutdown semantics. - Non-pauseable beans CountDownLatch adjustment to reflect pauseability constraints. - JDK 19+ related AutoCloseable issue in ExecutorService fixed to prevent resource leaks and ensure clean shutdown. Overall impact and accomplishments: - Improved runtime configurability and lifecycle reliability for Spring-based services. - Enhanced transactional consistency and event handling around BEFORE_COMMIT listeners. - Faster, more predictable startup/shutdown with reduced risk of paused-state inconsistencies and better task cancellation behavior on close. - Stronger alignment with modern library ecosystems, enabling easier adoption of newer features and performance improvements. Technologies/skills demonstrated: - Java, Spring Framework core lifecycle, bean proxying, and transactional semantics. - Hibernate ORM 7.1, Reactor 2025 development stream, Micrometer, Jetty, Netty, Protobuf, HtmlUnit, Mockito. - Build/dependency management and JDK compatibility strategies (JDK 19+).
