Unable to run jar file with –enable-preview flag when using corretto 17

I am trying to run my application in an ec2 instance using the command nohup java –enable-preview my-application.jar But somehow the –enable-preview flag is ignored and i still get an error on startup telling me that i should try running it with the flag –enable-preview. I use amazon’s corretto-17 as the openJDK version. Does corretto-17 not support the –enable-preview flag?

How do I install jarsigner on Amazon Linux 2?

Answer It appears Amazon follows the RedHat packaging scheme with JRE and JDK separated,
