      Windows 10 version 10.0.17763.557

      Java version "10.0.1" 2018-04-17
      Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10)

    • Yes

      The API method generateTree in class World will generate a ClassCastException when the target TreeType is RED_MUSHROOM or BROWN_MUSHROOM.

      To use the test plugin, left click a block to generate a red mushroom and right click a block to generate a brown mushroom. The clicked block must have enough room around it for a huge mushroom to grow on top of it.

      This bug has been tested on both Spigot and CraftBukkit on all Minecraft versions between 1.13.2 and 1.14.3. The bug appears in both Spigot and CraftBukkit for Minecraft 1.14.1 and is present in all future versions.
