[Feature Request]: Java 21 support for 1.12.2 version

[cygbs]

Is there an existing issue for this?

• I have searched the existing issues

Suggested Feature

When installed on 1.12.2 client or server, and use Java 17 or 21, it's will not work.

However, Such as https://github.com/CleanroomMC/Cleanroom for client, and https://github.com/HomoMC/Beast for server, work best on Java 21.

Some plugin and mod need Java 17 or above to load and work when running on 1.12.2, so, I really hope OTG support Java 21 on 1.12.2, or Java 17...

OTG requires Java 8 specifically for 1.12.2. There is a branch that attempts to build with modern versions of Java and Gradle, but it's not complete and I don't have the time to spend on finishing it
