Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
A weakness potion reduces your melee damage by 1 hearts. A melee punch is only half a heart, so this seems to me to be working as intended.
