Here they made a game engine (Minecraft) that manages to look crappier than a Quake 1/Quake 2 game while requiring a Core i7 for 'decent' runtime performance. Let's not even talk about the RAM hoging as well.
Seriously - that entire game underscores just how crappy Java is and why nobody in their right mind should be using it for games. People with over 8GB of RAM have to start dabbling around with changing their VM heapsizes just to get the game to run 'properly'.
I'm sure to you the end justifies the means though and all of this is 'just fine'. Everything must 'go Java' because... well, because some 'brogrammer' whose entire career depends on his 'job security' as a 'Java brogrammer' depends on it. No, your job security as a Java brogrammer is not sanctimonous - and people should call a spade a spade.
But then again it is a testament of the times that a game like 'Minecraft' is 'what is happening' today. Minecraft would have been laughed out of any serious game discussion even in the early 2000s - both in terms of performance and graphics. That you need a Core i7 with gigabytes of RAM for it would have been unthinkable back then and quite frankly they'd have found the whole thing to be goddamn ridiculous - which is what I still regard it as.
