Machine Agent error "Could not find the main class: com.appdynamics.agent.sim.bootstrap.Bootstrap. Program will exit."

[Lidiane_Wiesner]

Hello everyone,

I am using the Machine Agent without the bundle version 22.6 as indicated in past releases in docs. When I run java -jar machineagent.jar, I get the error:
Could not find the main class: com.appdynamics.agent.sim.bootstrap.Bootstrap. Program will exit.

I ran the command jar tf machineagent.jar | grep com/appdynamics/agent/sim/bootstrap/Bootstrap.class, and it shows up, so I don't understand what I'm doing wrong. Can you help me?

Hello @Lidiane.Wiesner,

What's the Java version on the host machine? I think it should be >= 1.8
Also, try providing the absolute path of java (i.e. >= 1.8) when starting the machine agent.

Hello @Lidiane.Wiesner,

I did some digging around and I've seen people suggesting to make sure java is running on a supported environment.
