Upstream has released updates that appears to apply and compile correctly.
This update has not been tested by PaperMC and as with ANY update, please do your own testing
CraftBukkit Changes:
aed3aecb Make natural item dropping mimic Vanilla
improved the water code so that immunity wont trigger if the entity
has the water pathfinder system active, so this improves support
for all entities that know how to behave in water.
Merged 2 EAR patches together, and removed an MCUtil method that
doesnt have a purpose anymore
