Generally speaking, SCJP questions have extremely precise answers, but thread questions, by the very nature of how threads get scheduled often CANNOT have such precise answers...
So, it's really common to see imprecise words in threads questions like: "probably" or "could" or "possible" or "tends" or "most likely". Of course it's essential that you pay attention when a question uses a word like that - it means that you can't exactly predict the outcome of some code, but that you can know some things about how it will run.
Spot false dilemmas now, ask me how!
