During the last three months, there have been some changes regarding Eclipse MicroProfile at Red Hat. If you haven’t been following the details, this post recaps what’s changed and introduces Thorntail and SmallRye.
Bye-bye WildFly Swarm! Hello Thorntail!
You may have missed this important news. Our MicroProfile implementation changed its name two months ago.
After a lot of feedback from the community, we decided to rename “WildFly Swarm” to Thorntail. While the former name was nice, we found that the “Swarm” term was a bit overloaded in the IT industry and could be confusing. It’s the same for the “WildFly” part; sharing this name with our Java EE application server was a source of confusion for some users, making them think it was a subproject of WildFly.

Every developer has the goal of building the most resilient application possible. Due to the distributed nature of microservices, resiliency and handling failures gracefully is mandatory. The Java ecosystem has some nice frameworks for fault tolerance, such as Hystrix or Failsafe. However, none of these provide a standard API, so using them means your application will be tightly coupled to that framework. The primary motivation for the MicroProfile specifications is to provide standard APIs that eliminates the tight coupling and improves deployment flexibility. This article will describe the main features of the MicroProfile Fault Tolerance specification, and then demonstrate how it was implemented in WildFly Swarm, the Red Hat MicroProfile implementation.

This article will show how to use a custom version of Hibernate (Hibernate ORM and Hibernate Search) on a WildFly Swarm Java application. I won’t give details about the WildFly Swarm configuration, if you need more information you can take a look at the WildFly Swarm User’s Guide.
WildFly Swarm includes fractions for Hibernate ORM and Hibernate Search.
You can add those fractions using:

At the beginning of October, I attended JavaOne in San Francisco to present on WildFly Swarm and Apache Kafka. For those of you that weren’t able to attend the session, or for those that did and saw first hand the issues with the demo, I will be covering all the details of how the demo should work!

“I used WildFly Swarm to shrink my app from 45 megabytes to only 2243 bytes.”
I was recently playing around with various techniques for packaging Java microservices and running on OpenShift using various runtimes and frameworks to illustrate their differences (WildFly Swarm vs. WildFly, Spring Boot vs. the world, etc). Around the same time as I was doing this an internal email list thread ignited discussing some of the differences and using terms like Uber JARs, Thin WARs, Skinny WARs, and a few others. Some folks were highlighting the pros and cons of each, especially the benefits of the thin WAR approach when combined with docker image layers.
