Minecraft Forums

So I was trying to get minecraft to launch up but as soon as it launched up it crashed. Then I checked to see what was wrong and i saw... well... take a look:

Vec3 Pool Size: ~~ERROR~~ NullPointerException: null

what dose this mean? Can anyone help?

No one knows how to fix problems like this, and your computers probbably just bad. This has happened to me and I just waited. It worked after a couple of days. The only thing to do is wait.

Here is full crash report:

So yes it was modded but I was testing a few things out and it just crashed.

By the way Idk why it crashed but i have Alienware so it probably isn't a bad computer.

hi

Is Modded: Very likely; Jar signature invalidated What? this is very strange BTW are you using ModLoader?

I think you have to remove forge and try again (because it shows that there is no mods)

ok thsi might help

1. check what ur java version is. I don"t think Java 8 is compatible.

2. is your launcher moded? if yes check ur mods and see if there updated

3. restart ur computer

That is not a full crash report, which will look like this; you can also look in your .minecraft folder (click on "edit profile" and "open game dir" for quick access) for a folder named "crash-reports" and open any files in there.

Also, the "error" you are referring to is meaningless and not the cause of the crash; it is "null" simply because it is only created when a world is loaded, but in your case it crashed during startup.
