- using Path.moveTo is more likely to be atomic, so that a concurrent process is less likely to find the jar being updated missing. (Alan: is there a better way to do the common task of replacing a file with its transformed output?) The moveTo method does have the ATOMIC_MOVE option for cases where you require it to be atomic but I don't think it is needed here. The transform into a second file and replacing the original seems fine, and probably the safest in that the original isn't trashed if something goes wrong.
