In the Project Reactor team, we believe that the debugging experience of the libraries you rely upon is as important as, let's say, the feature set or performance.

Today, we're excited to announce two new experimental projects in the Reactor family!

BlockHound - a new kid on the block

One of the most common rookie mistakes is to block Java threads that are supposed to run only non-blocking code (e.g., Schedulers.parallel()).

Hi Spring fans! Welcome to another installment of This Week in Spring! I'm in Pleasanton, CA, visiting one of Pivotal's large customers, and then tomorrow it's off to New York City for my talk there at the Kafka Summit with the excellent Tim Berglund and James Watters.

On behalf of the Spring, Apache Geode and Pivotal GemFire communities, I am pleased to announce the release of Spring Boot for Apache Geode & Pivotal GemFire (SBDG) 1.0.0.M4.

Special appreciation goes out to @starbuxman for his invaluable feedback after SpringOne Platform 2018. And, if you have not seen Josh’s Spring Tip video on Apache, please check it out.

What’s New

Among a few minor updates, Milestone 4 adds the following new capabilities:

• Externalized configuration support with Spring Boot’s Configuration Processor and SBDG provided @ConfigurationProperties classes (Read here for more details). Inside STS or IJ Enterprise addition, developers will have the added convenience of auto-completion and content assist.

• GemFire/Geode nodes can now be named with the spring.application.name property.

• The GemFire/Geode Spring Boot starters now include Spring Shell as a runtime dependency, which is convenient when enabling and using GemFire/Geode’s management services.

• Provided a workaround to an issue in Spring Cloud Commons .

On behalf of the team and everyone who has contributed, I'm happy to announce that Spring Initializr has been updated and is now available on start.spring.io.

UI changes - listening to your feedback

Following the last revision, the main feedback we received was about the missing list of dependencies. Some community members seemed to be looking at this list for information purposes (not necessarily using the website to generate a new app), while others would just like to see what's available.

While start.spring.io seems like a very simple service, generating applications with a simple HTML…
