I have been experiencing the same issue on version 1.2.5 with Java 8. From the looks of it, it looks like the S3 server the resources are saved to have been made forbidden for accessing by the general public, as the log kicks out a bunch of 403 errors. If the launcher is supposed to be having all older versions use the legacy assets, it doesn't seem to be doing that either as there is no sound in-game, even after waiting for all 403s to subside.

This is just one IOException kicked out by the game. All errors are exactly the same, just with t
the file name changed.

java.io.IOException: Server returned HTTP response code: 403 for URL: http://s3.amazonaws.com/MinecraftResources/streaming/cat.mus
	at sun.net.www.protocol.http.HttpURLConnection.getInputStream0(Unknown Source)

Extreme lag in the menus, feels like 5-10fps most of the time, sometimes slower. 3-4 seconds when clicking something. I have all render distance and effects turned down and makes no difference.

Confirmed for release 1.8

Still exists in release 1.8

The same is happening to me, except that it never loads the game.
