      What I expected to happen was...:
      I wanted to join a server hosted by some friends, but before I could do that I needed to change versions, updating from 1.10.2(with Optifine) to 1.11.2. I created a new profile, or whatever each separate version setting is called, and then tried to launch the version so Optifine 1.11.2 could install. I hadn't launched 1.11.2 before. I expected it to work fine and launch normally.

      What actually happened was...:
      The launcher stopped responding almost immediately when I hit the button to launch the game, and did so repeatedly across all my profiles. It crashed once trying to load the "default latest version" profile but afterwards, that one ran fine. I attempted to delete each profile and then just re-make them, but it just kept crashing.

      This had happened once with the old launcher, and in the JVM arguments text box, to make it run properly, I just needed to change the "-Xmx1G -XX:" text to "-Xmx2G -XX:" and then it worked perfectly. So, I checked this on the new profiles, and indeed the setting had turned to the Xmx1. So, I tried changing it back.

      I hit the save button and attempted to run the profile again, but then it spat back some message along the lines of it was trying to download features from an incompatible version; I didn't take a picture so I forget the exact text. I was able to get it running by just brute-forcing it again and again, but each time I had to go into the JVM arguments of every single profile, change Xmx1 to Xmx2, and try again.

      It took approximately 30 tries, and on a majority of those attempts, the launcher automatically reverted the settings back to the unusable default Xmx1 even though I hit the save button.

      Steps to Reproduce:
      1. Open the new Minecraft launcher.
      2. Create a new profile using version 1.10.2 and up(I didn't test for versions below, and the "Affects Versions" box won't let me choose anything but 1.11.2 and the snapshot).
      3. Attempt to run the game. It should immediately stop responding.
      4. Check the advanced settings of the profile. In JVM Arguments, the first few letters should read "-Xmx1G -XX:..."
