Having Server Startup Troubles on Mac.

[lolboi8]

So, I am running Minecraft on my mac and I installed forge on my client using the installer no problem. My friends and I wanted to play a modded survival together so I made a server (running the jar using start.command and everything, so I could connect to it and it was playable) and then used the same installer to install forge on the server (I used  the folder in which the server files were). Then i doubleclicked the forge server jar file and it made the mods folders, libraries, etc. Then I replaced the minecraft server jar in the start.command with the forge file and ran it again. It got somewhat far and then I got this error:

I also tried running the minecraft server jar in the start.command and it just launched without forge. Can anyone help me with this problem?

[lolboi8]

Also, I am running Mac OSX 10.6.3.

[luacs1998]

If not, update to java 7.

[lolboi8]

Looks like your Java installation is broken. Especially the ZipFile class.

 

How do you think that I should go about fixing this?

[LexManos]

Update to 9.10.0.846+

It was a small Java 1.6 incompatibility cpw introduced, an then fixed once he was made aware of it.

However, I do advise you update to java 7 simply because of the major security and performance improvements it has.
