- Description:
Since Java SE 6 is the only Java version shipped with Mac OS X 10.6 Snow Leopard, any application that requests an older version of Java will only launch in Java SE 6. No dialog is presented, since there is only one choice, and the app will either work correctly or it won't.

Workaround:
Ensure your application will run correctly on Java SE 6...

- Description:

Due to backwards compatibility constraints, older Java applications which are bundled with a PPC-only JavaApplicationStub will only launch in 32-bit Intel.

Workaround:

Rebundle the application with a JavaApplicationStub that contains an x86_64 slice in its mach-o binary.

- Description:

Applications that use Cocoa Java will fail on Snow Leopard.

Resolution:

Contact the application's developer for an updated version that does not use Cocoa Java. Cocoa Java has been deprecated since Mac OS X 10.4 Tiger in 2005, was only supported on Mac OS X 10.5 Leopard for 32-bit applications, and this support has been removed as of Mac OS X 10.6 Snow Leopard.
