Run configuration doesn't load

[cptspike]

Hi all, I've been modding with Forge for a while and it's all good, but today Eclipse refuses to run the Minecraft client. It was working earlier, I've changed literally nothing, and now all I get is this:

Java HotSpot 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release

 

I've tried removing and re-adding the run configuration, but it isn't helping. Anyone have any ideas?

I don't see an error here. Everything looks normal.

Your going to have to trace your code if you can.

That's just it. Minecraft never launches. No code is ever called. This happened before and I fixed it by manually adding a new run config, but this time no dice
