Pressing play in launcher, and quickly closing it leaves java process hanging and throws an exception

Is this still happening?

It's not throwing an exception anymore, but it leaves the process and launches Minecraft regardless.

That might be something we can improve upon. Thanks.

We need to check for a 'closed' state before we actually decide to launch mc.

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.
