Java Weekly, Issue 191

Lots of interesting writeups on Java 9 this week.

Here we go…

1. Spring and Java

===== >> Opening Up Java EE [oracle.com]

>> Oracle Looking to Move Java EE to Open Source Foundation [infoq.com]

The Java EE team is considering going to an open-source, third-party foundation.

I think that’s going to be a great step forward – I hope it really works out this way ?

>> How Java 9 Incubator Modules Will Change the Future of Java [takipi.com]

Incubator modules will be an interesting feature of the JPMS – they will allow a safe introduction of unfinished or experimental APIs.

>> Introducing Actuator Endpoints in Spring Boot 2.0 [spring.io]

Spring Boot 2.0 brings many important (and cool) changes to Actuators, along with the support for Spring MVC, Spring WebFlux, and Jersey.

>> Vavr, Collections, and Java Stream API Collectors [4comprehension.com]

It turns out that the Stream API Collectors can be used easily with Vavr (formerly Javaslang) Collections and even with tools like Option or Try.

>> Fast Forward >> Vavr 1.0 [blog.vavr.io]

The rebranded Javaslang is approaching the first full release under the new name – which will include numerous changes like splitting the main artifact into smaller ones, and Java interoperability improvements.

I always find it interesting to look at the high-level state of our ecosystem.

My one note here is that I would have liked to also see Clojure in there as well.
