Comment 4 for bug 287717

It doesn't cause a problem for me - it just doesn't enable acceleration (possibly because I use a laptop video chipset with dual screen). But for the average user it should work fine. AFAIK -Dsun.java2d.opengl=true is the recommended setting upstream. I can't see any reason why you would default to not using OpenGL acceleration? My problem is not with OpenGL acceleration, it is with the opposite - software rendering is very slow!

btw, I have also had problems with the JRE crashing editing large maps, I now use -Xmx1024M which has fixed the problem.
