Jenkins Continuous Integration Server not starting on Linux EC2 Instance

Question

I am facing a problem starting jenkins after an update on an Linux EC2 Instance. There was an older version of Java installed and i updated using yum command

    sudo systemctl status jenkins.service
    ● jenkins.service - Jenkins Continuous Integration Server

The java version details

java --version
openjdk 11.0.23 2024-04-16 LTS
OpenJDK Runtime Environment (Red_Hat-11.0.23.0.9-2.amzn2.0.1) (build 11.0.23+9-LTS)
OpenJDK 64-Bit Server VM (Red_Hat-11.0.23.0.9-2.amzn2.0.1) (build 11.0.23+9-LTS, mixed mode, sharing)

When i run the jenkins version command i get the below error

jenkins -version

I assumed that this was a Java issue so i tried installing the below Java versions i.e.

There is 3 program that provides 'java'.
