The second pre-release for Minecraft Java is now available. In this pre-release, we've upgraded the Java version that is bundled with the game, and the game now uses Java 17. Other than this, we've mostly been busy fixing bugs.

Enjoy!

Technical Changes in 1.18 Pre-Release 2

Minecraft now uses Java version 17. If you are using a default setup the Launcher will download and install the correct version. If you are using a custom Java setup or a third-party launcher, you will need to ensure that your Java installation is version 17 or above.
