Page History
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.

Features
These issues features will not be ported to OpenJDK from the Apple Java SE 6 port
- Making MacRoman encoding the defaultdefault 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
