Using incremental CMS is deprecated.

Ever since Minecraft 1.9 was released, I've been facing this problem every time I try to start the game. For example if I select the most recent version, 1.11, it will download all the assets like with all the other versions, and the launcher disappears like the game is about to start. Then the launcher appears again and a bunch of text that appears in the Game Output tab that says

"Can't find or load main class net.minecraft.client.main. Main
Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release"

I've tried to reinstall Minecraft and Java a couple of times to ensure that I have the latest and the most fresh version of everything, but this problem is still appearing whenever I try to play the game with the original launcher. Using a 3:rd party launcher like MultiMC or other works, but it makes things more complicated that using the original one.

Not a bug, it's a launch argument that won't get supported in the future, as such there's the warning.

But there is no solution for it?

Not a bug, so no solution needed, the message by itself is 100% harmless.

But it appears everytime I try to start the game. I can't play at all :|

I'll give you the Launcher Log just in case. https://pastelink.net/45ra

That's not the reason you can't play; "Game ended with bad state (exit code 1)" this is.

Search it, and you'llfind numerous reports, read them.

What does it mean?

All the tickets containing that message are resolved to MCL-137.

I'll see if I can find something there. Thanks!
