Microsoft ports open source Java to Windows 10 on ARM

Microsoft’s Java Engineering Group has reported progress in porting OpenJDK, or open source Java, to Windows 10 on ARM64-based devices, having completed the first phase of the initiative in late June. The company’s initial changes are being upstreamed to the OpenJDK project itself.

The port has been submitted to OpenJDK in partnership with Red Hat. An early access binary is available via GitHub. Microsoft said it has seen increased adoption of ARM64 on laptops and servers, with the architecture offering higher energy efficiency in data centers and battery life extension on personal devices.

How to Install OpenJDK 11 on CentOS 8

What is OpenJDK?

OpenJDk or Open Java Development Kit is a free, open-source framework of the Java Platform, Standard Edition (or Java SE). It contains the virtual machine, the Java Class Library, and the Java compiler. The difference between the Oracle OpenJDK and Oracle JDK is that OpenJDK is a source code reference point for the open-source model. Simultaneously, the Oracle JDK is a continuation or advanced model of the OpenJDK, which is not open source and requires a license to use.

In this article, we will be installing OpenJDK on Centos 8.

Announcing OpenJDK for Windows 10 on ARM | Java at Microsoft

Last year Microsoft announced the acquisition of jClarity to optimize Java™ workloads on Azure. This kicked off the beginning of our Java Engineering Group in Microsoft’s Developer Division, helping deliver on the vision of any developer, any app, and any platform.

Today, our team is excited to share that it has completed the first phase of porting OpenJDK™ for Windows 10 on Arm® (AArch64) based devices, and now we are in the process of upstreaming the initial changes to the OpenJDK project. The port, led by Monica Beckwith with support from Ludovic Henry and other engineers from the team and partners, has been submitted to the OpenJDK project in partnership with Red Hat. An Early Access binary is available via our GitHub project, and developers are welcome to download and try it.

Read Monica’s message to the OpenJDK mailing list.

Microsoft has seen great enthusiasm in the market and the increased adoption of ARM64 architecture on laptops, and recently on servers. With much higher energy efficiency, the use of ARM64 can drastically reduce the cost of data centers and extend the battery life of personal devices. For many workloads and user preferences, Windows is the OS of choice, and because of that, the Java Engineering Group moved forward with this port to support those users.

While still not 100% feature complete, this port is based on the OpenJDK tip branch (16+) and can run most workloads, including SPEC SERT – after our contributions towards the new platform combination gets accepted – and all of the SPEC Java suites. Developers can start developing Java on Windows 10 ARM64 compatible laptops, like the Surface Pro X, with the core Java extensions on the recently-announced Visual Studio Code for Windows ARM64 along with traditional tools like Apache Maven, Gradle, and others – check out the VS Code for Java May Update. More details on the current limitations of the port, and roadmap, can be found on Monica’s message to the OpenJDK project, and on the GitHub repo’s README.

While optimizing Java for Azure remains one of our core goals, it is crucial to share that we are involved in other initiatives to make the Java platform even better on areas besides the Cloud. Microsoft in itself is heavily invested in Java as it can be seen from this slide below, recently presented by Martijn Verburg at this year’s Microsoft Build session “Modern Java for Cloud Developers.”

Going Beyond Java 8: Local Variable Type Inference (var) - DZone Java

According to some surveys, such as JetBrains’s great survey, Java 8 is currently the most used version of Java, despite being a 2014 release.

What you are reading is one in a series of articles titled ‘Going beyond Java 8,’ inspired by the contents of my book, Java for Aliens. These articles will guide you step-by-step through the most important features introduced to the language, starting from version 9. The aim is to make you aware of how important it is to move forward from Java 8, explaining the enormous advantages that the latest versions of the language offer.

In this article, we will talk about the most important new feature introduced with Java 10. Officially called local variable type inference, this feature is better known as the **introduction of the word **var. Despite the complicated name, it is actually quite a simple feature to use. However, some observations need to be made before we can see the impact that the introduction of the word var has on other pre-existing characteristics.

An Open-Source Book About the Open Source World

Open source today is a word that often include a lot of things, such as open knowledge (Wikimedia projects), open hardware (Arduino, Raspberry Pi), open formats (ODT/ODS/ODP) and so on.

It is a world of opportunities that can be difficult for newcomers but also for intermediates. This article will help you discover how to approach specific roles, activities or projects/communities in the best way.

Everything Started with “Coaching for OpenSource Communities 2.0”

I decided to write a book in my personal style about my experience in the last 7 to 8 years in open source. I was surprised when I reached 100 pages about various different topics.

My idea was to write something that I would like to read, so nothing that is boring or complicated, but full of real facts.

The second goal was to include my experience but also my philosophy on contributing and how I contribute daily.

Thirdly, I wanted to give a lot of hints and resources and an overall view of this open source world.

Basically, I wanted to write something different from self-help or coaching books that includes just a list of suggestions and best practices. Instead, I take real examples from real life about the OSS world.

As a contributor and developer, I prefer to have real cases to study, because best practices are useful, but we need to learn from others and this world is full of good and bad cases to discover.

In 2019, I started writing a book after Fosdem 2019 and after 2 years inside the Mozilla Reps Council. In that Fosdem edition, I had a talk “Coaching for Open Source Communities 2.0” and after the feedback at the conference and my thoughts in various roles, activities, and projects, it was time to write something.

At the end it wasn’t a manual but a book that included my experience, learnings, best practices and so on in Localization, Development, Project Maintainer, Sysadmin, Community Management, Mentor, Speaker and so on. It contains the following sections:

  • Biography - This choice isn’t for self promotion but just to understand my point of view and my story that can be inspiring for others
  • Philosophy - Not the usual description of Open Source or the 4 freedoms, but just what Open Source means and how you can help
  • How to live inside the Open Source - A discovery about communications and tools, understanding the various kind of people and the best way to talk with your community
  • How to choose a project - Starting with some questions to yourself and how to involve more people in your project
  • The activity - Open Source is based on tasks that can be divided in 2 levels: Support, Testing, Marketing, Development etc
  • How to use your time - We are busy, we have a life, a job and a family but Open Source can be time-consuming
  • Why document is important - How writing documentation can be healthy for your community and the project’s future and brand

There are also three appendices that are manuals which I wrote throughout the years and gathered and improved for this book. They are about: community management, public speaking, and mentoring.

The book ends with my point of view about the future and what we have to do to change opinions about those topics.

I wrote this book and published in October 2019, but it was only possible with the help of reviews and localizers that improved and contributed. Yes, because this book is open source and free for everyone.

I picked the GPL license because this license changed the world and my life in the best way. Using this license is just a tribute. This decision usually is not clear because after all this is a book and there are better licenses like Creative Commons.
