I get this all the time now when either starting up modded Minecraft, or when creating a new world. Sometimes I'll also randomly get it after several hours of gameplay. This is happening with the Official Minecraft Launcher, with MultiMC and with the FTB Launcher, no difference. I have a 64-Bit Windows 7 machine setup with 8GB of RAM, and Java version 7 Update 45 installed, 64-bit version. This problem is getting worse and worse, causing me to have to restart Minecraft over and over and over just to get a viable session that doesn't bomb out on this error message.
I've tried completely uninstalling Java and reinstalling, I've upgraded it several versions as well. I have tried with JVM arguments configured and without, all to no avail. At the rate that this problem is progressing it is going to be impossible for me to play Minecraft of any kind within the week.
I'm desperate and aggravated, and looking for ANY help. I've reported the issue to Sun but they have no answers for me.[DOUBLEPOST=1383537381][/DOUBLEPOST]If this helps at all, here is the error report referenced above:
