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.
Javaslang, an open-source functional library that provides persistent data types and functional control structures for Java 8 and beyond, published a roadmap for a major release version 3.0 that promises significant changes to the library to remove unnecessary and deprecated features.
Lightbend surveyed over 2100 JVM developers to study correlations between development and infrastructure trends. Their findings, published in a whitepaper, revealed that microservices and lightweight containers are challenging heavyweight J2EE application servers.
Ceylon, RedHat’s strongly statically typed language for the JVM, has reached version 1.3.

Details of the new Scala Center, a non-profit organization created to focus on education and the open source community, were presented by research scientist Heather Miller during her June 16, 2016 keynote address at Scala Days Berlin.
Clojure has a new core library, clojure.spec, that aims to provide a standard and integrated system for the specification and testing of data and functions. Besides making it possible to automatically validate Clojure code, the new specification system can be used for a number of tasks such as generative testing, error reporting, and destructuring.
JetBrains has released IntelliJ IDEA 2016.1, the latest version of their most popular IDE. The new version seems to have the polyglot developer in mind, with multiple enhancements over a variety of languages and technologies; however, the most noticeable changes are aimed at Java, particularly at helping developers take full advantage of Java 8.
IBM has created Eclipse OMR, an open-source virtual machine toolkit to create runtime environments for any language. OMR aims at leveraging general improvements in virtual machine technology across languages, like garbage collection or hardware integration. To achieve this, IBM is generalising its own JVM, J9.
Jenkins 2.0 beta is now available which includes a new Pipeline build delivery system using a DSL built on Groovy. That feature and a new user setup process aims to give users most of what the need out of the box.
Brian Goetz has published the results of the local variable type inference survey and the results point to enthusiasm for adopting the feature. InfoQ looks at the results.
Last week, the Scala Center was created as a not-for-profit foundation, along with a list of financial backers, to improve the ongoing development of Scala and provide training courses based around the Scala language.
The company formerly known as Typesafe, inventors of the Scala programming language, has completed their renaming and is now known as Lightbend. Typesafe announced their plans to rename last May, stating at that time that it was expected to be a two month process. They invited community members to participate, and provided blog updates about their progress.
JetBrains has announced the first stable release of Kotlin, their new JVM-based language compatible with Android. As the maker indicates, the language is meant to be a "good tool", driving design decisions towards pragmatism and interoperability. The language promises to address many of the issues that can only be fixed in Java through libraries and external tools.
After three months in beta, the Kotlin team has announced the release of Kotlin 1.0, which aims to stabilize both API and ABI of the language. InfoQ has spoken with Andrey Breslav, lead Kotlin designer at JetBrains.
