[1.10.2] Crash when hit by a few modded projectiles

[Mach12]

Some projectiles such as Inventory Pets' Bananarang or Blaze and egg projectiles shot by a Lucky Sword seem to, very often, crash the game with varying stacktraces, but always with a ConcurrentModiticationException when ticking an entity, or something along these lines.

I've already cross-posted this to Inventory Pets' bug tracker in case it's, for example, a problem in the Bananarang, but I decided to post this here since it would seem that multiple mods' projectiles have the same problem of crashing when hitting the dummy. The ticket there has an example of crash log I get from this phenomenon, using the Bananarang.
