• JavaApplicationStub replacement

Features needing evaluation for distribution mechanism

• Crypto/Keychain/Smartcard

Features not in public macosx-port ("deploy" is private to Oracle)

• 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 cross-process CALayer connection mechanism to be exposed
  • Need to determine update mechanism (Sparkle.framework?)
• Web Start
  • Need to determine delivery vehicle (inside Applet plug-in, or some other form)
• Java Preferences

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

Non-Features

These features will not be ported to OpenJDK from the Apple Java SE 6 port

• MacRoman default encoding
  • UTF-8 only, for all locales/languages
• NSView-based AWT heavyweight widgets
  • LWAWT Swing-based widgets only
• NSView-based JAWT embedding
  • CALayer embedding instead
• CocoaComponent
  • Use CALayer-based JAWT embedding instead
• SWT Carbon EventLoop support
  • No 32-bit only technologies, Cocoa only
• JNI instantiation through the JavaVM.framework
  • Embed your own JRE instead
• Apple JavaApplicationStub
  • Use the new JavaAppLauncher, loads an embedded .jre, JavaApplicationStub compatible
