Re: Bundling a VM with OS X applications - unfortunately not!!

I agree with the issues you raise here, but I have not personally experienced an OS update breaking a Java implementation that was previously working. However it is routine to have to update or patch *nix OSs when updating Java implementations.

On the other hand I have on many occasions had applications break when updating Java.

That's not entirely true.

Binding a JRE with your product only statically binds to a JRE. It does
not statically bind to any of the shared-libraries that the JRE itself
calls, such as file-system functions, networking functions, graphics
functions, threading functions, memory functions, etc. Basically, this
includes everything that the OS itself provides as a shared-library,
framework, or system-call. Typically, that's a lot of stuff.

If there are ever any incompatible changes (bugs or fixes) to any of the
DLL's that the JRE calls, or in any aspect of the underlying OS, you're in
exactly the same boat as everyone else who didn't statically bind to a JRE.
The name of that boat is "OS-Reliant", and all you've done by binding to a
JRE is move the deck-chairs around a little.

You are still dependent on the QA and backward-compatibility skills of the
OS provider. You are also dependent on the skills of the JRE provider in
ensuring that a then-current JRE will continue to work on future OS
updates. Those are different shoals and reefs than relying on a JRE
bundled with an OS, but they are still able to sink an unwary craft.
