Usernames and folder names that match the ignore list break loading

[gigaherz]

The folder name C:\Users\rasmussen\AppData\Roaming\.minecraft contains the string "asm" in it, and so all libraries in the minecraft library repository are ignored. As a result, forge can't load.

The error:

A workaround is creating a new account without "asm" in the name, but this is highly inconvenient for most people.

Any explanation of why the string "asm" would induce this? Seems unreasonable.

[gigaherz]

It's due to the ignoreList written in the version json:

        "jvm": [
            "-DignoreList=bootstraplauncher,securejarhandler,asm-commons,asm-util,asm-analysis,asm-tree,asm,client-extra,fmlcore,javafmllanguage,mclanguage,forge-,${version_name}.jar",

The same would happen if your windows username was something like "forge-of-gods" since it would match the "forge-" ignore entry instead.

We've tried explicit version numbers, however modlauncher uses a wildcard and thus breaks that.
We need to make this a lot more robust, but still flexible.
Honestly we could try path.getFileName().startsWith() to be a bit more strict.
