hope this doesn't break any necro rules, found the thread when i got the handshake error.  I don't like the holes in java security so i don't have regular java installed however MC comes with java so you can install forge there. I got the error because I was using an older version of java within the MC folder (similar to the advice here about updating java) so I went back and checked the folder timestamps from when I updated to this newest version of MC. the java folder (for 1.19.2 at least) is called "java-runtime-gamma" and running cmd java.exe -jar forge.jar from /bin in this newest folder was successful.

What do you mean with "regular java" and which "java" did you use instead?

I didn't install java when I set up windows on this box so it isn't available to install forge, that's what was meant by "regular java".  Minecraft though comes with java that doesn't impact anything else except Minecraft (least as far as i can tell) and that is the java I used to install forge. my error popped because I had multiple versions of MC and I wasn't using the java associated with the version of MC I wanted forge associated with.

D:\Program Files (x86)\Minecraft Launcher\runtime is where the MC java is located for me. There are currently four java folders there: jre-x64, jre-legacy, java-runtime-alpha, and java-runtime-gamma. I used the x64 version out of habit which led to my error. I checked timestamps and saw the gamma version was what came with 1.19.2.  Copying forge.jar to that folder and running java.exe from cmd there was successful.

I think you mixed up the versions, but Minecraft 1.17 or above requires java 17.
Java 18 is not used yet by Minecraft, i'm sure it is compatible but i would recommend you to use java 17.
