Exception in thread "main" when building graph

[Rob Shaw]

Hi

I'm trying to get OTP2 running for the first time. When I try to build my network I get an error message. Can anyone advise if this is a known issue or how to get it working please?

Thanks

Rob

Run command: java.exe -Xmx32G -jar otp-2.0.0-shaded.jar --build --save graphs

Error during save graph progress:

Are you using Java 11?

I was just about to reply and say "yes of course I am" when I checked my PATH statement and it was pointing v16. Very sorry for asking a question before checking the obvious. It's working fine now :)

Thanks
