When you do a heap dump you get all the static values. The heap dump shows that static fields are in a special object for that class. You can access this "object" in the Sun/Oracle JVM by using the Unsafe class.
While local values are on the stack, eg. a reference, any object this references in on the heap. (Unlike languages like C++)
e.g.
String hi = "hello";
The reference hi
in on the stack but the Object (which is most of the memory) is in the heap.
static variables -> perm gen
local variables-> stack
