MicroProfile Becomes Eclipse MicroProfile
MicroProfile, the community initiative to provide a microservices standard for enterprise Java, has joined the Eclipse Foundation. The move is aimed at ensuring that MicroProfile remains a vendor-neutral project, and hopes to leverage the resources and momentum of the Eclipse Foundation. The decision has caused some arguments and temporarily diverted efforts from other objectives.

Java 9 Enters First Bug Fixing Round
Java 9 is now officially feature complete, meaning the first bug-fixing phase has started. HTTP/2 Client didn't make it on time for the deadline and has been downgraded to an incubating feature. Since the objective now is to prepare Java 9 for general availability in July, it is very unlikely that any new JEP will be added at this point.

New JEP Would Simplify Java Type Variance
A new JEP Candidate proposes to facilitate the handling of type variance in Java. The new proposal, potentially targeting Java 10, would add a means for specifying the default variance in the definition of generic types, different to the current style of indicating it through wildcards at instantiation. This proposal is not a replacement for wildcards, but rather a way to reduce the need for them.

Java 10 Could Bring Upgraded Lambdas
A new JEP proposes enhancements to lambda functionality, including better disambiguation, use of the underscore for unused parameters, and shadowing of outer variables. Although these changes would bring lambdas in Java closer to other languages', the community seems divided for now. This JEP complements a series of other proposals to improve the Java language with type inference and better enums.

Java Enums to Be Enhanced with Sharper Type Support
Java enums will be enhanced with generics support and with the ability to add methods to individual items, a new JEP shows. Since both features can be delivered with the same code change, they are bundled together in the same JEP. The change only affects the Java compiler, and therefore no runtime changes are needed. Although there is no target version, Java 10 seems likely.

Java Type Inference Won't Support Mutability Specification
Java type inference won't support differentiation of mutable vs immutable variables due to lack of consensus within the community regarding how this should be implemented, recent communication shows. Also, to prevent a long debate about corner cases, a number of such cases will be ruled out. Although the JEP doesn't indicate a target version, Java 10 seems likely.

Is Gartner's Report of Java EE's Demise Greatly Exaggerated?
Gartner has produced a report called “Market Guide for Application Platforms”, citing Java EE’s “revenue decline” in reporting “a clear shift” in the application platform market. The Java EE community takes issue with those findings, in personal comments to InfoQ.

Latest Java 9 Schedule Appears to Be at Risk from the Outset
After approving the feature extension process, Oracle has confirmed July 2017 as release date for Java 9. Similar to a previous estimation by InfoQ, the new schedule involves a longer wait time for feature extension and impacted testing phases which may impose a risk. Early, informal testing might be in place to compensate.

RxJava 2.0 Released with Support for Reactive Streams Specification
The RxJava team announced their 2.0 release after an 18 month development cycle. The project's "What's Different in 2.0" is a good guide for those developers familiar with RxJava 1.x. This release brings an important milestone. RxJava is a sub-project of ReactiveX, which is "a combination of the best ideas from the Observer pattern, the Iterator pattern, and functional programming".
