This week's giveaway is in the EJB and other Java EE Technologies forum. We're giving away four copies of EJB 3 in Action and have Debu Panda, Reza Rahman, Ryan Cuprak, and Michael Remijan on-line! See this thread for details.
f3 refers to f1.f, so f1 is not eligible for gc. Further, f1.f refers to f2, so f2 also is not eligible for gc. So... is it that both options are correct (i.e. no object is eligible for gc at GC point 2)?

Got it. Just ignored the simple fact. Since nothing is returned from the method, all the objects created in the method should be available for GC. Additionally, nothing is persisted in the static field. Thank you guys.
