Haven Error!

Hello.
I had a working salem "executable" until now. Now,when I want to connect to the server (server status seems up, and also I havent made any change into my Operating system). This error I have with enders and also with default client.
Details on error:

Java version is 7 and I run it under Linux ( I havent tried yet in windows)
Is the problem from my side?
