Error on Javachat

[Midori no Nebula]

If this is misplaced, sorry in advance.

So yeah, here's an error I've just been getting while trying to join #bulbagarden, now that my connection is stable... for now.

[13:27] Connecting...
[13:27] Error : Not connected
[13:27] Unable to connect : java.security.AccessControlException : access denied (java.net.SocketPermission lava.systemnet.info resolve)

Any idea what's going on or how to sort it? I've tried refreshing but no luck. D=
