For about 2 weeks now my copy of Minecraft crashes on world load/create. The launcher starts correctly but when I click Singleplayer and load a world (or create one) it freezes on generating terrain and crashes.

I've tried deleting everything under the .minecraft folder, reinstalling java, nothing works.

Crash report (pastebin): Click here

If it doesn't work here's the crash report:

    The link does not work. – Skye Jun 6 '15 at 2:45
  • ^^Yeah, we're getting a '403 Forbidden' error when we click that link. Perhaps you haven't made the paste public? You can edit your post here, paste the crash, select it, and use the brackets button "{}" to format it into a code section :) – Robotnik Jun 6 '15 at 7:25
  • Its not even pastebin – Universal Electricity Jun 6 '15 at 14:33
  • the link its proxied because pastebin is blocked on my country, it works fine for me (i use safari for windows). Anyway i'll use the "{}" button, thanks. – Azov Jun 7 '15 at 1:32
  • Can you put your java version? – Universal Electricity Jun 12 '15 at 9:46

Judging from your stacktrace (The list of all the event that lead up the error) , your Java or possibly minecraft is having an issue with your network. It cannot access something it needs to continue.

At this point there are a few things that could cause it. But tt is hard to narrow it down from this point because minecraft's code is obfuscated and the error report is cut off by the crash handler.

  1. Troubleshooting your firewall or if you have a proxy, tinkering with that.
  2. Verifying your Java is installed correctly may help also.
  3. Another alternative could be that this is caused by Minecraft attempting to open the world to LAN as soon as it is created. And this would be an issue with your router/modem not having a properly setup LAN network.
  4. You have launch options that are interfering with the connection information, such as a proxy for your minecraft client. You can disable these in the minecraft launcher if you have them set.
  • I tried the thing about the firewall, i permited minecraft completly. Java its installed correctly. My router is the same as when my minecraft worked correctly. No launch options. – Azov Jun 7 '15 at 2:08
  • If you have access to your router, check for any firewall issues their. Unless that is what you already meant. – itotallyrock Jun 7 '15 at 2:11
  • That is what i already meant. But thanks anyway. – Azov Jun 7 '15 at 2:14
  • It said you were using minecraft 1.8.6 at the time of the error, have you tried to update to the latest version? – itotallyrock Jun 7 '15 at 2:19
  • If none of these work, you can backup your old .minecraft in your %appdata% and then delete the whole folder. Afterwards relaunch minecraft. If for some reason any file is conflicting with your minecraft, this will fix it. – itotallyrock Jun 7 '15 at 2:27

after reading your stacktrace i think you are missing some files

try to clear each and every file of minecraft not by just .minecraft by your c drive and desktop too remove each and every file of java and then reinstall 32 bit java if you are using cracked minecraft if you have puchased minecraft then use 64 bit java reinstall minecraft and try it i mean that you just refresh each and every file related to minecraft if it dont work consult your problem with mojang

  • How are you getting the stacktrace? And if you say remove every file with .class or .java, some people who do work with java will be affected. – Universal Electricity Jun 6 '15 at 20:08
  • I removed all the things related to minecraft and java on my PC, i uninstalled java and reistalled, i have 64 bit java for purchased minecraft, i dont know what to do. Sorry for my ignorance, but what its the stracktrace? – Azov Jun 7 '15 at 1:49
  • @Azov The stacktrace is all the at something.something(SourceFile:1) – Universal Electricity Jun 7 '15 at 18:13

In my case, I used a proxy app to bypass the security on my network. I turned the app off and my problem was solved.

I've encountered the same problem as you and my solution was to disable the windows firewall through Services>Windows Firewall> "Stop"
