Calling a Java function from C++ using CNI

Of course, just because I don't believe it's true doesn't mean it
isn't. The following code works!

[HelloWorld.cc]
#include "HelloWorld.h"
#include <gcj/cni.h>

int
main()
{
	JvCreateJavaVM( NULL);
	HelloWorld::hello();
	return 0;
}
[EOF]

What does JvCreateJavaVM accomplish? Could it be called lazily, simply
called the first time a Java object is created or a Java static
function is called?

Thanks,
Shaun
