      I downloaded the server 1.7.2 jar from the minecraft.net site, tried to fire it up, and got the following:

      $ java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui
      Exception in thread "main" java.lang.VerifyError: (class: net/minecraft/server/MinecraftServer, method: v signature: ()V) Can only throw Throwable objects
      

      (The file was named minecraft_server.1.7.2.jar when I downloaded it; I tried renaming it; creating a symlink to it, etc. – it doesn't seem to affect the result; also, I tried reinstalling Java, but that didn't change anything, either.)

      One other tidbit: when I try to start the client, I get the conjugate error,

      Exception in thread "main" java.lang.VerifyError: (class: ban, method: f signature: ()V) catch_type not a subclass of Throwable at net.minecraft.client.main.Main.main(SourceFile:72)
      

      I tried the 1.6.4 server jar, and it hits this problem:

      ...

      and then it stops the server.
