title: Failed to find Premain-Class manifest attribute for java agent
body: <p>I am trying to run a java agent. My docker file to create container:</p>
  <pre><code>FROM ${my_repository}/open-jdk:1.8.0.262.b10-el_8-2020.09.15-1
  
  ENV AGENT_HOME=/usr/local/agent
  ENV AGENT_CONF=&quot;$AGENT_HOME/conf&quot;
  
  COPY jmx_javaagent.jar $AGENT_HOME
  
  WORKDIR $DOMAIN_ROOT
  
  ENTRYPOINT [&quot;./start.sh&quot;]
  CMD []
  </code></pre>
  <p>And start script addsjmx parameters to jvm parameters. As a summary in the script:</p>
  <pre><code>...
  java -javaagent:${AGENT_HOME}/jmx_javaagent.jar=${AGENT_PORT}:${AGENT_CONF}/config.yaml \
           -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.port=${JMX_REMOTE_PORT} \
        
  </code></pre>
  <p>When I run the image on kubernetes, I am getting :</p>
  <pre><code>Failed to find Premain-Class manifest attribute in /usr/local/agent/jmx_javaagent.jar
  </code></pre>
  <p>So what is wrong here ?</p>
