Server NoClassDefFoundError

Title: Server NoClassDefFoundError

Version: 3.1.2

OS: Windows XP x64 Edition (SP2)

Java Version: JRE 7 u6 x64

Description of Problem:

Since updating to 3.1.2 I and alot of others cannot start their servers. It will run on a Windows 7 x64 machine, but no longer on my XP x64 machine, prior to updating it would run on any, so it must be a problem with the update. A search for this issue reveals many people in the same situation.
