So today is my first day downloading Technic and I wanted to play some pixelmon, so I installed the pack, hit play, then it does its thing. Then i get this notification saying "You've selected Java 12.0.2, which is known to have issues with Minecraft. Are you sure you want to continue?" I hit yes and then it does nothing and nothing pops up. I've been dealing with this for an hour now, I need help.
