Have java 8 update 333 64-bit installed.

you can replace java in the .bat/.sh file with the full path of the executable java.exe of java 8

This actually worked, thank you so much, any idea why it wouldn't just work with just java in the command line if 1.18, 1.19 and 1.15 servers just work?

1.18, 1.19

these two version requires java 17, i think the JAVA_HOME is set to java 17 in this case

1.15

i have no idea 1.15 requires java 8, means the same error of 1.16 should ocoure
