INTERNAL EXCEPTION: BAD PACKET ID 128 Preventing Online Play On A Server

INTERNAL EXCEPTION: JAVA.IO.IOEXCEPTION: BAD PACKET ID 128

This error makes it so that I cannot play online on my friends server. He has to restart the server in order for me to join again, and it just happens a couple hours later anyways. We updated the server to 1.4.3 for a test and now when I join, my game crashes once I click join server. We are currently on 1.4.2 and still not possible for me to join, It also seems like that who ever is on with me at the time that I get the error, also gets kicked out of the game, they can join back, but then they might get the same error just as I, like its contagious! It sure does seem that way, now we all get the error after a couple hours and it wont stop.
