  Features not yet ported from Apple's Java SE 6

  • Bundled app launching
    •  JavaApplicationStub replacement
      •  Stub source now checked in. More tools for bundling an app are coming.
      •  Stub and AWT reviewed for sandboxing
        •  need to fix JavaSound, launcher stub, and remove dependency on X11 libfreetype.

  Features not in public macosx-port ("deploy" is private to Oracle). You'll have to trust us on these – deploy is not ready to be open-sourced.

  • Applets/Plugin2
    • Need to create .plugin bundle
      • Need to embed slimmed JRE into .plugin bundle
    •  Need NPAPI/Cocoa event -> Java event conversion
    • Need the LWAWT to render into NSOpenGLLayer (see above)

    •  Need to determine update mechanism (Sparkle.framework?)
    •  JavaFx support
  • Web Start
    • Need to determine delivery vehicle (inside Applet plug-in, or some other form) – Java Web Start.app will find javaws in the deployment bundle and execute that. Requires at least 10.7.3.
    •  Shortcut support
  •  Java Preferences 
    •  UI cleanup: Look better on Mac OS X
    •   Preference pane

  Non-feature tasks

  • Merge BSDPort into mainline jdk so that Mac OS X Port can be inserted into mainline:
    • Merge BSDPort hotspot, patch and description at: BSDPort, Description of jdk7 changes
  • Move internal bugs to http://java.net/jira/browse/MACOSX_PORT
  • Write up development wiki pages for
    • Quickstart
    • Status
    • Compiler changes/issues
    • Cocoa & Java crash course
    • Threading manifesto
    • Memory management manifesto
    • AppKit Threading & Cocoa Memory Management best practices examples
    • Internal "Adopt-an-app" testing workflows
  • Port private JUnit harness tests to jtreg
    • Detailed status
