HotSpot Hacking

I'm trying (unsuccessfully) to add a method to the Unsafe class.
As a start I'm trying to duplicate an existing method.
I add the declaration of the new method to, and update
unsafe.cpp as well.
I register the new method in unsafe.cpp and vmSymbols.hpp, following the
example of the original method.

Then I compile the jdk, and want to test the change.
A test program, which uses the new method, compiles but fails to run due to
an UnsatisfiedLinkError.

So my question is, what are the steps of adding a native method to HotSpot?
Is there is some tutorial or documentation available?

Thanks in advance,

Best Regards,
