method-local inner classes

I'm just preparing for the scjp/ocp and in the chapter about the inner classes (SCJP Sun Certified Programmer for Java 6 Study Guide I, p. 670) there is this code example:



I understand all lines, but my question is: It's right that the inner object will be carbage collected (but with no garantee) after the method doStuff() completes?

Since the variable inner goes out of scope at the end of the method, there are no other references to the object and the object is not passed out of the method, then yes, it's eligible for garbage collection.
