Comment 10 for bug 1126349

Just got this today:

If its any indication, This was while running spigot (a minecraft server), and it uses 'plugins' (as jars). I had just recompiled a new jar, and scp'ed it and overwrote the old plugin .jar while the server was running. I only got this error when i told spigot to shutdown. maybe its related to the jar (a zip file) being different then when it was first loaded and it freaking out?
