MC-18494The Minecraft Server crashes if run from a directory containing a '!' in it's name
You cannot have '!'s in your user name / profile name, this breaks java horribly. This is something we cannot control or fix You can fix it by not having '!'s in your user name / profile name name.

When minecraft_server.exe or minecraft_server.jar is put into a directory with a name containing the character '!', it crashes with a java.lang.NullPointerException straight away.
This is obviouslyt not intended, and it took me quite a while to understand why my server wouldn't run.
Steps to Reproduce:
1. Make a directory called '!' (or anything containing it)
2. Put minecraft_server.exe in it.
3. Run and watch it never open.
I've tested this on both jars and exes, snapshot 13w25b and 1.5.2.

You cannot have '!'s in your windows profile name, this breaks java horribly.
This is something we cannot control or fix
You can fix it by not having '!'s in your windows profile name.

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
I know it’s a template text, but yes, of course this is still an issue, no-one from the developers team actually cared about that issue so far.
