Slides

File:Jdk7-jvmls-2009.pdf

Project Coin

• project to evolve the Java language
• improved integer literals
• "exotic identifiers": #"op~"
  • for interoperation with langugages that may use symbols and such in method names and other identifiers (ex: Scala)

Project Jigsaw

• modularization of the JVM
• JVM is too large (18MB), slow to download not on broadband, hard to fit on small devices
• ex: import the 'desktop' module, get swing, sound, awt, etc.
• jmod tool to quickly install packages:
  • sudo jmod install [url for .jmod package] and you're done

mlvm

• Da Vinci Machine Project
• explored further in the next session
• goal is to support multiple languages well on the JVM
