Does Minecraft even support Java 14?

[modmuss50]

Once ASM 7.2 is out of beta we can update to support j14

[Sollace]

Last I checked Minecraft didn't even support Java _9_. I highly doubt 14 is anywhere remotely possible.

Minecraft is known to be able to run as high as Java 12, though it only explicitly supports Java 8. I don't much doubt that it could run on Java 14 considering Java's extreme distaste for any sort of breaking changes.

[modmuss50]

Java 13 is known to work.

The reason 14 doesnt work is due to the requirement of ASM 7.2, if you really want to use it you can use the beta but for now stick to 13 and bellow.

The current recommended version is 8.

According to Chocohead's reactions in fabricord, Minecraft itself will work with Java 14, but ASM7.2 is the primary bottleneck here.

Clean unmodded Minecraft 1.14.4 works fine on Java 14.

Pr open at https://github.com/FabricMC/fabric-loader/pull/160
Since this is related to the loader than the api, closing.

"Clean unmodded Minecraft 1.14.4 works fine on Java 14." - A bit off-topic, but... out of curiosity, does it not expose the same ConcurrentModificationException problems some users saw on Java 9 ~ 12?

There is also a problem with something apparently trying to process java.* with asm, this shouldn't happen in the first place...
