Over the years, Oracle has been making big investments in Java for ARM-based devices.
This week, Oracle and ARM announced further expanding their collaboration on a number of fronts, from additional hardware platforms, porting layers, and optimized communication protocols, to 64-bit ARMv8 support, and IoT architectures.
Henrik Stahl, VP of Product Management in the Java Platform Group at Oracle, just posted an excellent summary: “ARM TechCon 2013: Oracle, ARM expand collaboration on servers, Internet of Things”. Highly recommended reading.

Just back from Brazil and no time to catch my breath … so much happening:
- JavaOne Latin America was a blast – so much enthusiasm in the developer community! Check out some of the videos and podcasts, including the JavaOne Community Keynote, OTN interviews with a variety of Java luminaries, as well as the Java Spotlight Podcast #60: JavaOne Latin America: Videos and Podcasts
- Java 7u2 has been released, featuring an updated VM, support for Oracle Solaris 11, support for Firefox 5 and later, and security fixes. Also, JavaFX 2.0.2 is now included with Java SE to make developing and running JavaFX applications even easier: Java SE 7u2 Release Notes, JavaFX 2.0.2 Release Notes
- Aligning with mainline JDK development, Java SE Embedded 7u2 has been released as well. This release includes new ports to Linux on PPC and performance improvements on ARM systems by 20-40%. Also, Oracle intends to port JavaFX to Linux on ARM in order to support a broad range of platforms from mid-range embedded all the way to desktops: Henrik’s blog on the Java SE Embedded 7u2 release.
- Lots of activity around JavaFX as well – interest is really taking off. Point in case: A new project, eFX, has been started on java.net aiming to create a generic application framework for JavaFX 2.0 based on the NetBeans platform: Geertjan’s blog on eFX
- Finally, OTN put together a list of their “Most Popular Tech Articles of 2011”. Java topics, from Java SE 7 and 8 features, Java EE 6, JSF, and JavaFX dominate the list. Have a look: Our Most Popular Tech Articles of 2011
A few weeks ago at JavaOne, Oracle announced its intention to open source the JavaFX platform.
To that effect, Oracle yesterday proposed to the OpenJDK mailing list the creation of the OpenJFX Project as the home not only for the JavaFX source code, but also for current and future development of the JavaFX toolkit in an open development model.
This is a significant step for the JavaFX technology and the OpenJDK project and demonstrates quite clearly Oracle’s commitment to open source, transparency, community building, and the success of JavaFX.
Some info on the planned OpenJFX contribution:
- Over 6000+ public API members (methods/constructors/etc.)
- Over 11,500 unit tests
- Core libraries such as observable collections and binding
- Scene graph, effects, graphics
- CSS support for JavaFX
- Prism (hardware accelerated graphics, including openGL and D3D and java2D implementations)
- Glass (windowing system, base porting layer, including mac, linux, and windows implementations)
- UI Controls and Charts
More background information can also be found on the FX EXPERIENCE blog.

Finally, I get a chance to catch my breath. JavaOne has been extremely busy and while there are still a few hours of good talks to go here is a quick summary so far:
The vibe is very positive. Attendance is significantly up over previous years and the show is well organized. Feedback from attendees has been very excouraging – lots of good buzz on #javaone and other social channels. Many sessions are sold out or standing-room only.
This year’s JavaOne left no doubt Java is moving again, and picking up steam. Throughout the conference and in the various keynotes there was a host of announcements, strategic initiatives, roadmaps, product releases and updates.
I’ll try to summarize, focusing on the Java Platform, Java SE, and Java ME technologies:
Java SE and the Java Platform:
- Oracle announces plans for advancing the Java SE Platform, including a vision beyond JDK 8
- A JDK 7 for Mac OS X Developer Preview is now available, with full developer and consumer releases planned for 2012
- NetBeans 7.1 Beta is now available, featuring full Java SE 7 support
- Oracle details plans for JDK 8, proposed features, and a revised roadmap with extended scope, now scheduled for availability in summer 2013
- Oracle is continuing its work to merge the HotSpot and JRockit JVMs, with the first converged features available in JDK 7
- IBM announces availability of Java SE 7 across its products lines, the faster ever adoption of a new Java SE release by IBM

After speaking to many developers over the past days it’s clear JavaOne has brought renewed excitement and energy to the Java community. I personally am particularly excited about Java FX 2.0, the Mac OS X support for JDK 7 and JavaFX, and bringing Java ME back to the mainstream platform again.

- Oracle shows JavaFX on iOS and Android (MacWorld)
Some quick updates and links that have accumulated over the past days:
- The Expert Group on Project Lamba (“Closures for Java”) decides on the syntax. Check out Brian Goetz’ posting to the EG mailing list.
- Apple posts a new developer preview of “Java for Mac OS X 10.7 Update 1” and “Java for Mac OS X 10.6 Update 6”. See the post to the OpenJDK mailing list by Mike Swingler from Apple.
- Scott Kovatch announces starting at Oracle and his return as Technical Lead on the Mac OS X port of OpenJDK. Read his blog post “An old new beginning”.
- Josh Marinacci writes about client-side improvements in Java 6 and 7, including Swing, graphics, AWT, look and feel, installation and start-up, and more. Read the full OTN article
With the release of JDK 7 people have been asking “Where is JDK 7 for Mac OS X?”.
Apple and Oracle engineers are currently actively working on integrating the OS X Java code base into OpenJDK. This initial integration takes time and we can’t yet give you a specific date on the completion.
However, the integration is coming along well. You can check out the details of the Mac OS X Port Project within OpenJDK, see the status on the project wiki, and follow the mailing list. There are also regular (but unofficial) builds available for download.
PS: Of course, you can still always get the official Apple OS X JDK 6 implementation through the OS X “Software Update” mechanism.
Beyond the numerous new features of NetBeans IDE 7.0, version 7.0.1 adds full JDK 7 support, integration of recent patches, and performance improvements. Find all the info and download here.
Also, listen in to our recent Java Spotlight Podcast episode 41, which features Geertjan Wielenga, Principal Product Manager for NetNeans.
Yes, I know, I’m a bit late (I was on vacation for a week) – OSCON is already over. I didn’t attend myself but I heard there was a lot of good content at OSCON Java – some of which is already published on YouTube.
Here are just a few of the ones I found interesting (and I’m sure there’s more):
- Patrick Curran: “Who needs Standards?”
- Jim Weaver: “JavaFX in the Real World”
- Bob Lee: “On the Cusp of a Java Renaissance”
- Josh Bloch: “Java: The Good, Bad, and Ugly Parts”
- Steven G. Harris: “Open Source, Java, and Oracle – Cracking the Code”
