Hello all! I've just wanna update to 1.9 version and after all is finished, I got this error log at Game Output tab, instead of launching the game.
It's look like this:
"Error: Could not find or load main class net.minecraft.client.main.Main Java HotSpot(TM) Client VM warning: Using incremental CMS is deprecated and will likely be removed in a future release"
Note: I'm using Team Extreme Launcher 3.5.1
