Selecting a language no longer changes it in-game/crash the game

This brings me to crash the game.

The game is not crashing here but loading the resources several times:

When I reinstall the game(Delete the .minecraft), and click the "Language" button.
Game output:

'Version 3 resource packs have to use lowercase filenames for everything' maybe it happens because of this?? Language codes look like 'en_US' but they must look like 'en_us'.

At least the crash is fixed in the next version.

When reinstalling the 1.10.2, can fix crashes.

Confirmed fixed for 16w32b
