EnderPearlPlus is the Spigot plugin that aims to fix problem -
ender pearl bug. That bug causes ender pearls to "forget" their owner if the player exits and re-enters the game while the pearl is in mid-air. As a result, when the ender pearl eventually lands, it fails to teleport the player, breaking the expected gameplay mechanic.
I.e. this plugin helps ender pearls remember it's owner.
As a bonus it's adds ability to customize ender pearl behaviour such as allowing teleporting from other worlds
