Yes
This error occurs frequently, but non-deterministically: 21 times in the last 7 days. It is usually associated with the same chunk, which is the spawn chunk in a Multiverse world, but other chunks have been reported, including one in a non-spawn area of the base world. The worlds were identified by review of the saved regions in each world; in all cases to date the identified region had been saved in only one world.
No players have been connected during these incidents (they are test servers).
I tried unsuccessfully, for several days each, to produce the error with vanilla MC and CraftBukkit. Since it occurs on average 3 times daily, I am reasonably confident that – while it may not be a Spigot issue per se (see SPIGOT-5194ArrayIndexOutOfBoundsException) – Spigot is required to generate it.
