Agenda
• Java history
• Java‟s position
• Java SE 8
• Java Embedded & ME
• The future of Java SE (FX/ME)

5. 5
Java essentials
• Object Oriented
• Robust
• Multi-Threaded
• Network savvy
• Interpreted and Portable (WORA)
• Architecture neutral (wherever it runs, it runs the same)

6. 6
2007 – Java‟s heyday

7. 7
2007 Heyday of Java
• JavaOne biggest developer event in the world
• Java both Hot and Cool!
• Java headed for dominance on any device
– Mobile options open
• FX revolution started (=> TV, Blu-Ray, designers)
• Gaming and Virtual Worlds (Wonderland)
• Java to become open source (OpenJDK)
• JAVA was the Nasdaq Stock Symbol for Sun

15. 15
What happened in recent
years?
• JVMs
• JVM languages
• JVM platforms (WOR-oqafp)
• FX
• Java Community
– Vendors
– The rest of us
– Kids

16. 16
Many JVMs
• Zing
• Zulu
• BEA JRockit
• Sun HotSpot
• Apache Harmony
• IBM J9 VM
• Kaffe
• Jikes RVM
• JamVM
• Excelsior JET
• IcedTea
• OpenJDK

17. 17
Oracle‟s Converged JVM
roadmap
• Merge Sun HotSpot & BEA JRockit => Oracle HotSpot JVM
– Use HotSpot as the basis for the future JVM
– Cherry-pick features and port
– Same JVM for everything from embedded all the way up to
enterprise
• Make JRockit tooling available with unified
HotSpot JVM
– Mission Control & Flight Recorder (7u40)

18. 18
JVMs on [m]any platform[s]

19. 19
Oracle‟s platform roadmap
• Target platforms are
– Desktop Client
– Enterprise Server
– Mobile (feature phones) and Embedded devices
• No [plans for] JVM on iOS or other tablets or smart phones
– However: Embedded JVM in iOS and Android Apps
• No Java Applet browser plugin
– [please] No more Applets!

25. Java SE 8
• Description
- CLDC 8 is an long-anticipated, evolutionary update for CLDC 1.1.1 to bring
the VM, Java language and core API libraries in alignment with Java SE 8
• Key Features
- Synchronize Java SE 8 language features into Java ME
- CLDC 8 is an extended strict subset of Java SE 8
- Introduce developer-friendly Java SE APIs
- Includes updated Generic Connection Framework (GCF) 8
- Virtual Machine update to align with Java SE developer tools
- Remain small and enable footprint optimizations
- Backward binary compatible
- Enable 9+ Million Java developers to develop for Java Embedded
CLDC 8 High-Level Overview
CLDC 8
Bringing The World of Java SE to Java ME

26. 28
Many “JVM” languages
Java
Clojure
Groovy
Java
Script
Scala
JRuby
Jython

27. 29
Languages that can run
on the JVM

28. 30
Java 8 „theme‟:
Interoperability on JVM or The Polyglot JVM
• Easier interoperability between Java and other JVM languages
• Project Nashorn: very fast JavaScript engine embedded in JVM
– Available from Java code to execute JavaScript
– Allows JavaScript to invoke Java as well
– “Oracle is in the process of developing node.jar, a java implementation of node.js to
also run on the JVM via Nashorn”

29. 31
Story of FX
• Started as F3 by Chris Oliver
• Announced at JavaOne 2007
– And every JavaOne since
• Java FX Script 1.0 December 2008
• 2.0 release October 2011
– (no more FX Script)
• FX 8 – March 2014
– Included in OpenJDK
– To replace Swing
– On desktop & embedded
