Ghost keyboard inputs / sticky keys

While playing, the game randomly keeps me moving in a direction i was moving in till i press escape key. haven't had this issue since 1.1. this glitch bug did not occur for me at all in 1.3.2.

What i expected to happen: i move in a direction, releases the key, i stop.

What did happen: i move in a direction, i release the key, i keep moving in that direction till i press escape.

Tried upgrading lwjgl and java. doesn't help. Optifine use to fix this issue but on a seperate install i still have the same issue. I believe it's due to some sort lag between the client and the internal server.
