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”)

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.
