If I want to download the Minecraft JDK exe, I have to enter an Oracle account with number, company name, etc. Can i work around this?
Incidentally, the JDK is not a product specifically linked to Minecraft (since you are writing from Minecraft JDK).
You don't need a JDK from Oracle. Every other OpenJDK distribution does the same, the best known are AdoptOpenJDK (future Eclipse Adoptium) and Amazon Corretto. If you want it to be the old Java 8, as usual with Minecraft, and you are using Windows:
https://adoptopenjdk.net/?variant=openjdk8&jvmVariant=hotspot
or
https://corretto.aws/downloads/latest/amazon-corretto-8-x64-windows-jdk.msi
You don't need an Oracle JDK for this.
Just use an OpenJDK, it works for me without any problems
