   Issue with application starting with SBT, if play application start with `sbt run` or `sbt testProd`, agent could not send data to backend because of below exception, which is caused by extension class loader.
   
   `Caused by: java.lang.ClassNotFoundException: Can't find org.apache.skywalking.apm.agent.core.plugin.interceptor.enhance.InstanceConstructorInterceptor`
   
   As explained in https://github.com/apache/skywalking/issues/5242#issuecomment-671032068 extension class loader not support yet,
   
   In order to fix the issue, run play application in production mode (https://www.playframework.com/documentation/2.8.x/Deploying).
   
   Step 1 : Run on play project  `sbt dist`. It will create zip file in `target/universal/my-first-app-1.0.zip` folder.
   Step 2 : `unzip my-first-app-1.0.zip`
   Step 3: run `bin/my-first-app` from terminal with `-javaagent` arg.
   `bin/my-first-app -J-javaagent:/home/aamrute/work/tool/skywalking/8.5.0-es7/apache-skywalking-apm-bin-es7/agent/skywalking-agent.jar=agent.service_name=your_application_name`
