When in Adventure mode playing a map i noticed that i was able to mine the wood with the axe in my hand, i looked into it and it turns out that axes can mine wooden items like wood, planks, chests etc. pickaxes can mine stone and ores shovels can mine dirt and stuff, and well you get the idea. tools are able to mine their respective blocks even while bieng in adventure mode where you arent suppossed to be able to mine blocks.
What I expected to happen was NOT to be able to mine blocks in adventure mode.
What actually happened was that i COULD mine blocks (With the tool specifically meant to mine it)
Steps to Reproduce:
1. Set yourself to adventure mode
2. Use an axe, pickaxe, or shovel to mine the blocks that they are suppossed to (eg. Axe -> Wood)
MC-2367 Players can place and remove arbitrary blocks in Adventure mode, breaking pre-1.4.2 maps
