A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException

Description
When trying to execute the ServerStartLinux.sh I keep getting the same error. Google is full of it, but the solutions give don't seem to help. I'm sure it's a well known/minor thing but this is my first time trying to set up a server and it seems like I'll need some help.
I've installed openjdk 17.0.9 (17.10.2023) and downloaded the official minecraft_server.1.12.2.jar from mojang and placed it inside the E2E extended folder. Serverstart.log and installer.jar.log both look good to me, ending with server installed successfully and sever started respectively.
Edit: I thought maybe openjdk 17.0.9 is not the right one even through it is the most recent I can get through apt-get. I manually installed openjdk 21.0.1 but still get a slightly different error.

To Reproduce
Steps to reproduce the behaviour:
- download and unpack the server.zip
- install openjdk
- execute the ServerStartLinux.sh
Modpack version v1.26.0
1.12.2 Minecraft can only run on Java 1.8
Try to remove newer Java versions and install Java 1.8.
In other problems - I can't help. I don't know how ServerStartLinux.sh script working, I just copy-pasted it from the E2E. So you might try to find solution in E2E discord or E2E subReddit.
To be sure it's not E2E-E problem exclusively you can try to run E2E server.
I just tried with Java 8 but still get the same error. I'll go and ask on discord, it's probably more appropriate there.

That implies you are not properly changing java version - java 8 literally cannot produce this exact error
