Spring Shell shipped three critical fixes overnight that restore custom Converter bean handling and fix command registration bugs that broke in recent releases.

Spring Shell landed the most urgent fix: user-defined Converter beans were being completely ignored by @Command-annotated methods [1], a regression that forced developers to work around the framework's own dependency injection. The same release also fixes command completion for positional arguments [2] and eliminates eager instantiation of scoped beans during registration [3], both of which could cause unexpected lifecycle violations in production. On the Spring Tools desk, a null pointer exception in CompositeASTVisitor got patched [4], hardening the visitor pattern against null inputs with proper @NonNull annotations. Spring Session continues steady maintenance: Dependabot configuration got cleaned up [8], and the stack bumped three key BOMs including Reactor 2025.0.5 [5], Spring Data 2025.1.5 [6], and the security release plugin [7]. Spring Boot caught two test-side issues: a missing null check in ApplicationContextAssertProvider [9] and a typo in test method names [10], both already merged.

→ Pull Spring Tools patch to eliminate NPE risk in IDE tooling spring-projects/spring-tools [plan]
→ Review Spring Session BOM updates (Reactor, Spring Data) in next dependency sweep spring-projects/spring-session [monitor]
