Resolution:

Java Preferences are now honored when choosing a compatible JVM to launch a Web Start application.

Radar #5903263

Under certain conditions, the apple.awt.useScreenMenuBar property would not be honored in Web Start applications.

Description:

If a JNLP-based application was launched, and did not require Java Web Start to re-execute in another JVM version or architecture, the apple.awt.useScreenMenuBar property would not be properly initialized for that application, and it's menu bars would show up inside their windows.

Resolution:

The useScreenMenuBar property is now read much later in the application's initialization, and is now properly set.

Radar #6195034

The JVM architecture preference is not honored if the JNLP encoding is "utf-8"

Description:

A Web Start application will launch in 32-bit, even if Java Preferences prefers a 64-bit JVM if the JNLP file has a "utf-8" encoding.

Workaround:

Specifying the "arch=x86_64" option in the resources section of your JNLP file will force Web Start to run in 64-bit mode. Alternately, the JNLP encoding can be set to "macintosh".

LaunchServices

Radar #6220719

Input Method Hotkey does not launch.

Description:

Launching /Applications/Utilities/Java/Input Method Hotkey.app results in a dialog that indicates the application is not supported on the system's architecture.

Workaround:

From the command line, "touch /Applications/Utilities/Java/Input\ Method\ Hotkey.app", or use the Finder to "Show Package Contents" for the Input Method Hotkey.app bundle and run the Contents/MacOS/Input Method Hotkey executable directly.
