    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

      •  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

    • Write up development wiki pages for
      • Quickstart
      • Status
