title: vServer Linux - Start jar: Invalid or corrupt jarfile
body: <p>I'm running a Linux vServer with Debian 8.0 64 bit with
  512 MB RAM and 150GB space.</p>
  
  <p>Its planned to use it for a game and let a Server.jar run nonstop.
  The Server is working with Kryonet, a library for simple Client/Server communication. On my server i installed Java 1.8 and its working fine, for testing i downloaded Minecraft server jar, it works perfectly.
  So i packed my Server into a executable jar with eclipse (compile version 1.8), it worked fine when starting it with cmd on my computer (Java 8 installed) but when trying to start it on the server: <strong>Error: Invalid or corrupt jarfile Server.jar</strong> </p>
  
  <p>I thought it could be a problem with the librarys i used, so i tried a clean HelloWorld jar, also does not work.</p>
  
  <p>Here is a screenshot showing my installed java version and trying to run my HelloWorld jar.
