alright it's me again, i still don't know how to solve this problem. I have a 7 year old dell computer, and every time i try to launch a version past 1.7.2 the little white screen pops up and says the problem is outside of the java virtual machine or whatever. I've been working on this for a while now, and strangely the problem isn't really affecting gameplay on other computers. is it some kind of virus? maybe some sort of software glitch or something? please help! this is really inconvenient because there are tons of servers that run 1.8 and up. all answers are appreciated!
