Java Edition:Invalid Data Value Water Bottle
For 4 snapshots, updating potions did not properly convert their data value to the NBT tag potion system.[1] This allowed for water bottle items with an invalid data value.
Obtaining
This works by simply updating any potions from 1.8.9 or before to between 15w31a and 15w32a (1.9 snapshots). 15w31a changed the format of potions from data values to NBT tags, however, it did not check to convert the data values from the previous versions into the NBT tags. This means that the data value still exists on the water bottle, but provides little functionality, while able to be drunk and used in a brewing stand both these actions revert the bottle to DV 0. This was fixed in the 15w32b and the invalid data value water bottles were converted to their respective potions.
