This ticket is invalid as it relates to a modded or 3rd party client/server.

Any non-standard client/server build needs to be taken up with the appropriate team, not Mojang.
Any plugin issues need to be addressed to the plugin creator.
This site is for addressing issues related to the base unmodded MineCraft.

Oh, sorry I thought that if the client was not modded and the server was I should still post a ticket.

Your client:

Is Modded: Very likely; Jar signature invalidated

So you have a modded client. This includes such things as optifine and mcpatcher.
