Is it possible to find the source for a Java native method?

Question

I have found the clone() method of Object in Java:

 protected native Object clone() throws CloneNotSupportedException;

Answer 1

I found these files, but all they do is import the function from elsewhere. I can't find the actual source (try asking a Hotspot dev).

Object.c jvm.h

Edit: Here's a link to the actual source online (Thanks user439407 for finding which file it was in)
