[MCL-17210] Optifine doesn't launch with alternate jre

Steps to reproduce:

Install OptiFine.
Use any other jre than the one bundled with the launcher.
Try to start the game. The game won't start.

Observations:

This is only after a recent launcher update.
This only affects OptiFine installations.
I also tried using Minecraft Forge installs but it doesn't affect it.

But this is a launcher issue. It works fine when I use the bundled JRE that comes with the launcher by default. But when I try to use openJDK it doesn't launch the game.

Going ahead and re-resolving this as a duplicate of MCL-17220 as it appears to be an issue for any modded installation, not just optifine.

Thanks for pointing it out! 🙂

After further testing this issue is only relevant with fabric and optifine. Minecraft Forge works fine.
