Hello.
Yesterday, I went to check if Optifine for 1.7.2 was out yet (it was, yay). So, I installed Forge #982 (YESTERDAY, keep reading!) and put OF in the mods folder. I started Minecraft. First, I noticed an FML exception in the dev console, though Minecraft was still running fine. I decided to go play some multiplayer, and logged in. Just after MC connected to the server, I started getting a huge error spam from Netty. This spam totally made my whole computer lag, so I killed the process (couldnt just close it normally, the lag was so bad).
Today, I decided to investigate on the problem. I installed the newest Forge #985 (OF still there), and ran MC. I got the FML exception again. Still fine. Logged onto a server, and that spam started again. Killed the process, took OF out from my mods folder and run MC again. Got that exception and the same spam again. Tested if this was a vanilla bug, but no. Doesn't occur with vanilla 1.7.2. The spam is quite bad, as it may lag your computer really badly after a couple of minutes. Wishing that this bug report is enough to get it fixed!
I have made some research about the bug, but have found absolutely nothing. Couldn't get a ForgeModLoader-client-0.log, as it was from 1.6.4 (.newminecraft\1.7.2\logs\latest.log doesn't show the exception), so I got the whole Dev console log.
LOGS:
MC Developer Console: (WARNING, VERY LONG) [NOTE: I have taken about 1000 lines of that spam away to fit it on the forums. I can provide the full logs via Dropbox if needed.]
\Roaming\.newminecraft\1.7.2\logs\latest.log: WARNING, ALSO VERY LONG
