Per MC-138093 comments, ForkJoinPool uses unlimited threads if parallelism is ever 1. A 2 core machine will end up with 1 with the change I had previously made, so bumped the min to 2 so we will never trigger the unlimited thread situation. This aligns the min back with Spigot, but allows use of more threads on systems with more cores.
