get "ClassNotFoundException: org.apache.sling.launchpad.app.Main" when trying to run aem-author-p4502.jar on ubuntu. I got a quickstart.jar and license key for development from Adobe.i renamed it to aem-author-4502.jar and if I double click on it on my windows laptop, it works.My laptop is not strong enough to run AEM as well as my dev tools, so I am trying to run it instead on my dev linux box.Its ubuntu 20.04 LTS.I installed the oracle version of java 11:aem@author1:~/author$ java -versionjava version "11.0.9" 2020-10-20 LTSJava(TM) SE Runtime Environment 18.9 (build 11.0.9+7-LTS)Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.9+7-LTS, mixed mode)JAVA_HOME is set to /usr/lib/jvm/jdk-11.0.9/the box has 2 CPU and 4GB ram, and 32GB SSD free. It has nothing else running and is headless.If I try to start the jar thusly:aem@author1:~/author$ java -jar -XX:MaxPermSize=256m -Xmx1024M aem-author-p4502.jarThen I look in the stderr log file I see: Low-memory action set to forkUsing 64bit VM settings, min.heap=1024MB, min permgen=256MB, default fork arguments=[-Xmx1024m, -XX:MaxPermSize=256m
