    Description

      In MC 1.17, Cauldrons can now be filled with lava. https://minecraft.fandom.com/wiki/Cauldron#Lava_Cauldron

      It is defined as follows in org.bukkit.Material.

      /**
       * BlockData: {@link Levelled}
       */
      LAVA_CAULDRON(4514, Levelled.class),
      

      However, in reality, the lava cauldron is only full, and its data is not Levelled.


      TestCode:

          @EventHandler
          public void on(PlayerInteractEvent event) {
              Block block = event.getClickedBlock();
              if (block != null && block.getType() == Material.LAVA_CAULDRON) {
                  Levelled data = (Levelled) block.getBlockData();
                  data.setLevel(2);
              }
          }
