Hi, Spring fans! Are you using Java 21 in production already? No? you should listen to this episode. Yes? Then you should listen to this episode! This week, Josh Long talks to legendary Java Language Architect Brian Goetz (@BrianGoetz) recaping the latest-and-greatest and previewing Java.next

On behalf of the Spring Framework team, it is my pleasure to announce that the first Spring Framework 6.1 release candidate is available from repo.spring.io/milestone now.

Spring Framework 6.1.0-RC1 ships 75 fixes and improvements.

New Features

This first release candidate ships a few new features:

• Spring Framework 6.1 requires now a Jackson 2.14 baseline and supports the new DatatypeFeature
• We have made further AOT improvements, reduced the runtime reflection and prepared Framework for upcoming reachability changes in GraalVM
• You can now use an OutputStream as a source of data in reactive web APIs, thanks to a new BodyInserter method variant
• Functional web frameworks now allow headers manipulation when serving static resources; this makes it easier to write HTTP caching response headers.
…

On behalf of the team and everyone who has contributed, I am pleased to announce that Spring Framework 6.0.13 is available now.

Spring Framework 6.0.13 ships with 34 fixes and documentation improvements, including 7 fixes for regressions. This version will be shipped with Spring Boot 3.0.12 and 3.1.5, to be released next week.

We expect the next set of Spring Framework maintenance releases to ship next November, along with the new and exciting 6.1.0 we have been working on the last few months.

Part 3: Synchronizing with External Transaction Managers in Spring Cloud Stream Kafka Applications

In the last three sections of this blog series, we analyzed how transactions work in Spring Cloud Stream Kafka applications. We encountered different contexts in which transactions are helpful, including both producer and consumer applications and how an application can correctly use them. Now that those fundamental elements are behind us, let’s move on to another aspect of transactions: rolling back a transaction when an error occurs. When an error occurs and a transactional system cannot commit the transaction, the transaction manager rolls back the transaction and does not persist anything for a downstream consumer to see. It would help if an application could dictate how this rollback mechanism works. Spring Cloud Stream facilitates this rollback…

Hi, Spring fans! Welcome to another installment of This Week in Spring! Last week I was in Antwerp, Belgium, for the amazing Devoxx Belgium event, and this week I've been in Amsterdam for the SpringOne Tour Amsterdam stop and - in the middle of the SpringOne Tour Amsterdam event - I dipped out to join my friend and fellow Java Champion Trustin Lee (@trustin) (he created Netty! the guy's a living legend!) for a discussion and ask-me-anything at the local Amsterdam Java User Group, hosted by fellow Java Champion and local Geertjan Wielenga (@GeertjanW). It was a lovely day indeed across the two…

Part 2: Producer Initiated Transactions in Spring Cloud Stream Kafka Applications

In the previous part of this blog series, we saw the basics of transaction management, primarily when using producer-initiated Spring Cloud Stream Kafka applications. In that discussion, we also briefly saw how a Spring Cloud Stream Kafka consumer application could consume records produced transactionally with proper isolation levels. When you synchronize with external transaction managers, such as one…
