Please accept my apologies. I acted too hastily.

Yes, but the function is called JvCreateJavaVM, which is clearly
misleading. I have no intention of creating a VM. I therefore believed
the link did not apply to me. May I suggest JvCreateJavaRuntime? That
I would have believed.

I've read that object creation and static function calls check to see
that the class has been initialized first. Perhaps at this same point
the system could check that the runtime has been initialized.
