Again, no reason to store the TNTPrimed entity. Just call it directly in the event.

````
// CraftBukkit start
ExplosiveFuseStartEvent event = CraftEventFactory.callExplosiveFuseStartEvent((TNTPrimed) entitytntprimed.getBukkitEntity());
if (event.isCancelled()) {
    return;
}
// CraftBukkit end
