  • 5. 6 2007 – Java‟s heyday
  • 6. 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
  • 7. 8 The sky seemed the limit
  • 8. 9 Dark clouds were gathering took forever… Smartphone and Tablet revolution – closed platforms Android (Dalvik VM) left Java fold New Kids on the Block - scripting languages, anything new/hot How do you make money with Java tm?
  • 9. 10 Sun set
  • 10. 11
  • 11. 13 The Future in 2009
  • 12. 14 The Future as it happened and/or looks like today
  • 13. 15 What happened in recent years? • JVMs • JVM languages • JVM platforms (WOR-oqafp) • FX • Java Community – Vendors – The rest of us – Kids
  • 14. 16 Many JVMs • Zing • Zulu • BEA JRockit • Sun HotSpot • Apache Harmony • IBM J9 VM • Kaffe • Jikes RVM • JamVM • Excelsior JET • IcedTea • OpenJDK
  • 15. 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)
  • 16. 18 JVMs on [m]any platform[s]
  • 17. 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!
  • 18. Java 7 on OS X and Linux/ARM Ethernet USB SD Card Audio RCA Video General Purpose I/O Power HDMI Image source: Boston Ltd., UK
