[MC-9289] Hitting mobs with a sharpness I wooden sword and weakness III crashes the game

I gave myself all different sword types, none of which even register as punching with the weakness III effect active, then I wanted to try enchantments and noticed that no matter how low of a sharpness/smite/bane enchantment I put on anything it would always register as a punch (smite and bane only against the representative mobs).
(I will create another issue about this where I will go into detail about how this works)

To test if this still did damage I put a sharpness 1 on a wooden sword and started smacking a small slime, after doing so for a bit I figured that it didn't do damage but continued for the fun of it, until my game decided to crash.

This ticket is invalid as it relates to a modded or 3rd party client/server.

Any non-standard client/server build needs to be taken up with the appropriate team, not Mojang.
Any plugin issues need to be addressed to the plugin creator.
This site is for addressing issues related to the base unmodded MineCraft.

The gameclient is vanilla, therefore it is a vanilla minecraft bug.

Adventuremaps use custom potions (which are a feature of the game, specificly added to be used in the way I did) therefore this should be fixed and not ignored.

Is Modded: Very likely; Jar signature invalidated

If this can be reproduced in vanilla this can be reopened.

Reproduced in the vanilla client after doing a forceupdate.

TMI does not matter since it can be obtained legit but via a third party program (eg. MCEdit). Jens had done that specifically for adventure map makers

Please show that file to Mojang, NOT just this screen!

Yes now it looks good thanks 🙂

Further testing reveals it's the sword.
