I will be speaking at the goto: conference, in Prague in the Czech Republic, on Nov 22 and 23 – doing two talks:
- The keynote “The Future of Java”
- A session on “Embedded Java: Smart, Connected, Pervasive”
I hope to see you in Prague. If you haven’t registered yet, you can use the promotion code “oracle” and get a €100 price break.

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:
General observations:
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.
Announcements:
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
- Oracle recently announced availability of Java SE 7 for Embedded on ARM and x86 platforms
OpenJDK:
- OpenJDK hosts the development of JDK 7 for Mac OS X, JDK 8, and becomes the reference implementation for Java SE 8 and beyond
- Twitter joins OpenJDK
JavaFX and Rich Client UI Technology:
- The JavaFX 2.0 GA for Windows is now available
- A JavaFX 2.0 for Mac OS X Developer Preview is now available, with GA releases planned starting 2012
- NetBeans 7.1 Beta is now available, with JavaFX 2.0 support
- Oracle details JavaFX roadmap to 2013, including cross-platform support for Mac OS X and Linux
- Oracle announces plans to open source the JavaFX platform in the OpenJDK project
- A private Beta for JavaFX Scene Builder is now available, with public Beta planned in early 2012
- Oracle announces Project ‘Avatar’: A complete solution for Dynamic Rich Clients, including HTML5 support and back-end integration
Java ME:
- Oracle increases investment in Java ME
- Oracle Java Wireless Client (OJWC) 3.1 is now available
- Oracle announces plans to evolve the Java ME Platform and align Java ME with Java SE 7 through:
-
- Submission of new JSRs over the coming months
- Updates of the CLDC Platform VM and library specifications to enable better alignment with Java SE 7 features
- Creation of a “CDC Profile” in Java SE 8, which allows deployment of Java SE 8 implementations in resource-constrained environments
- JavaFX to become the graphics framework of choice for mid-range and high-end embedded platforms
- Oracle announces intent for full coverage of embedded vertical markets
- Oracle plans increased and deeper integration of Java ME with content services (“Mobile Services Integration”)
For more information and details, please see the related press releases:
- Oracle Continues to Move Java Forward and Details Java SE 8 Roadmap

Summary
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.

Next week, Tuesday, July 19th, the Wroclaw JUG in Poland will be hosting me for a Java 7 event – as part of the worldwide series of local Java 7 Launch events (see The Java Spotlight for an event near you).
The title of my session is: Java SE 7: The Platform Evolves. I’ll be talking about how the Java platform is changing and adapting, what’s new in JDK 7 (Project Coin, NIO2, Fork-Join Framework, The DaVinci Machine, and more), doing some demos – and hopefully we have time for a good Q&A session (and some beer 😉
I’m looking forward to it. If you’re in the area, please stop by. See the event page for more information.
