      The bug

      See title, the tool is not getting a Damage value when it is also setting Unbreakable.

      Loot table used to test:

          "pools": [
                  "rolls": 1,
                  "entries": [
                          "type": "item",
                          "name": "minecraft:fishing_rod",
                          "functions": [
                                  "function": "set_nbt",
                                  "tag": "{Unbreakable:1b}"
                                  "function": "set_damage",
                                  "damage": 0.5

      The log file returns the following:

      [20:27:25] [Server thread/WARN]: Couldn't set damage of loot item 1xitem.minecraft.fishing_rod

      Code analysis

      Using MCP1.12 names, in method net.minecraft.world.storage.loot.functions.apply(), it checks if the item can be damaged using isItemStackDamageable(), which returns false if the item does have a damage value but is set to Unbreakable. It could check instead if getMaxDamage() isn't 0.
