Okay. I recently bought a new computer, Its BRAND new and has 12 gigs of RAM. I'm sure its plenty. Anyway, on 1.9 I tried making a new world and see the updates my self. While loading, I see empty chunks and BAM. Crashes. I don't know why!? I have an Intel CPU Core i5-6000 @2.70 GHz.
I have the error report in this entry. Also note this. I DO NOT crash on 1.8 or any of the pre-1.9beta snapshots. ALTHOUGH. I do crash on the snapshots and 1.9 its self.
