I have just updated my Java via Software Update.
In my program the currently used Java version is displayed in the
about box. I am using System.getProperty("java.version") and
System.getProperty("sun.arch.data.model") to collect this information.
I specified 1.4+ as the target VM version, and I set version 1.4.2
as the most appropriate version of the Java VM to use in the Java
Preferences panel.
Surprisingly my program always starts with the 64-bit VM (version 5
or 6 depending which one is placed higher in the preference list).
Command java -version returns expected version number, i.e. 1.4.2.
My program uses universal JNI library compiled for 32 and 64-bit
architectures.
Isn't that strange?
Nope, new policy. We only select a Java version that is compatible
with the architecture your app has launched as.
Try checking the "Run in 32-bit mode" checkbox in the Get Info window
of your app in the Finder.
If you want that checkbox checked by default, check out the
LSArchitecturePriority section of the Launch Services release notes <http://developer.apple.com/releasenotes/Carbon/RN-LaunchServices/index.html
>. If you don't support 64-bit at all, strip the x86_64 slice out of
the JavaApplicationStub before you copy it into your app bundle.
Hope this explains what you are seeing,
