If Minecraft.net is affiliated with the devs and mods here, someone mixed up the links on the following site:

https://feedback.minecraft.net/hc/en-us/articles/29100721259021-Minecraft-Java-Edition-1-21-1

The site for the .jar and for the bug tracker is the same: they both point to the .jar link.

Please delete this bug if this is not the correct forum/issue tracker to post it in.

Thanks.
