This page outlines the status of high-level feature areas to bring from Apple's Java SE 6 to the Mac OS X port of JDK 7u4.
7u4 is now complete; 7u6 is in active development in jdk7u-dev.
A list of popular open issues is available at the JIRA bug reporter.

Cocoa key/text events
cleanup to use JRSEvent API
merge JDK6 CWindow -> LWCWindow changes and style flags
update CImage
Transparent window support
Headless
remove $AWT_TOOLKIT=CToolkit, switch to default
threading cleanup
Aqua LaF

Fonts/Text drawing
Needs cleanup to use JRSFont API
Accessibility
Clipboard
Drag & Drop
InputMethod support
AppleScript javax.script engine
Sound
Printing
Keychain Provider
JAWT (for SWT/3D embedding)
Smartcard
Fix Kerberos code to read config info from SCDynamicStore (needed on Lion) | http://java.net/jira/browse/MACOSX_PORT-566]
AWT Desktop API
System Tray
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 cross-process CALayer connection mechanism to be exposed
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
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
- Apple native crypto
- Use standard Java crypto
- HotSpot Shared Archive Generation
- Automatic JSA creation is of limited use until HotSpot supports class sharing in 64-bit, and in all garbage collectors
