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.
Censum, the Java garbage collection analysis tool by jClarity, has reached version 3.0. The main new features of the new version include the ability to analyse Safepoint logs, new graphs showcasing the behaviour of the G1 garbage collector, and a set of analytics to highlight whenever applications force to much OS activity.
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.
In a recent communication, Mark Reinhold, Chief Architect of the Java Platform Group at Oracle, suggested a six-month delay for the general availability of Java 9 so as to allow some extra time to finish project Jigsaw. After deliberation, the delay was accepted, setting the general availability of Java 9 to March 2017.
Oracle's Java Chief Architect Mark Reinhold has proposed delaying the release of Java 9 for 6 months to allow for more complete testing of the modularity features at the heart of the release.
Avian is a lightweight, portable, embeddable virtual machine that aims to support a reduced subset of Java on iOS alongside Linux, FreeBSD, and Windows. Version 1.2 added support for ARM64 on Linux and iOS.
At QCon San Francisco, we offer two days of workshops (Nov 19-20). Workshops focus on developing the technical skills that leverage technologies you heard about from our expert practitioners during the conference sessions. Here is a glimpse at some of the experts you can learn from QCon SF ‘15 workshops.
Frege, named after the German mathematician Gottlob Frege, is a purely functional, strongly typed language for the JVM that is so similar to Haskell that “most idiomatic Haskell code will run unmodified or with only minimal, obvious adaptions”. InfoQ has spoken with Ingo Wechsung, Frege’s creator.
As previously mentioned on InfoQ, Oracle had proposed JEP 248, about making G1 the default garbage collector, to be included in the list of JEPs targeting Java 9; recently, Oracle has confirmed such decision and made it official. The decision triggered a lengthy debate in the HotSpot’s email discussion list, which concluded with a provision to defer the change if G1 proves not to be fully ready.
Oracle is considering including JEP 248, making G1 the default garbage collector on server configurations, into the list of JEPs targeting Java 9. The decision has triggered some debate among the Java community, with many arguing that the CMS collector could have been more suitable.
Twenty years ago today, Java's first alpha release was unleashed upon the world on Solaris. InfoQ looks back at the history of Java and what it has conquered since.
Oracle has ceased public availability of security fixes and upgrades for Java 7, urging users to migrate to Java 8 or to purchase commercial long-term support for Java 7.
Plumbr shift its flagship product from a memory-leak tool to a JVM monitoring solution, adding thread contention detection, inefficient GC behaviour monitoring, and historical JVM data. InfoQ talks with Pritt Potter about this decision.
Oracle have announced more features to be delivered as part of JDK 9, including Unified JVM Logging and fine-grained control over the JIT compiler. Primitive specialization of generics is pushed out to JDK 10, however.
