Launcher crashes Java/Cannot create directory 'resources'.

[jadenquinn]

Before I even get to use the launcher, I get this Java crash. This is before anything on the launcher window loads, still being a white screen.
This is on a Mac Pro (2008) with upgraded GPU (still happens on original 8800 GT), upgraded (kind of) RAM (667MHz instead of 800MHz, but 8GB over 2GB, still happens on original 800MHz RAM), and I checked the readme and it said to rename the laucher_profiles.json (or delete it or something), but this had zero effect. Still crashes at the exact same time in the same way.

Ok this is strange. I went to try and see if I could launch the launcher jar using Java 8 update 301 instead of 371 or whatever it was launching with before, so I used Terminal to do so, and it appears to work now, no idea why. Still crashes on J8U371/whatever though.

Weird. Can you try another jvm? This may be upstream from the launcher, seems jfx-related.

Ok great now I got stuff to download, but the game won't launch.

Btw that's what I did in my previous comment which worked. There is a new problem now.

Hmm, that backtrace is not super debuggable. It's gotta be some permissions issue, but I can't be sure from what's there.

It wouldn't be a terrible idea to migrate olauncher to using the new file IO APIs, but until that happens, we're going to have to debug this another way. Can you create the resources directory yourself? Is it write protected? Is there some reason java wouldn't be able to write there?

Have the same issue here. I created the resources directory manually but still error, checked that it is not write protected and couldn't find any reason why java cant write in there. The directory is the default .minecraft directory in %Appdata%. Also tried with a custom game directory but same error. Other launchers using the same jre (1.8) are able to write and read no problem
