title: IntelliJ IDEA 2020.1.1 won't start
body: <p>I am using IntelliJ IDEA Community Version 2020.1.1 on Ubuntu 18.04 LTS and it is not starting. I tried running it from the terminal, the following error is shown:</p>
  
  <pre><code>OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
  Unrecognized option: -ide.win.frame.decoration=true
  Error: Could not create the Java Virtual Machine.
  Error: A fatal exception has occurred. Program will exit.
  </code></pre>
  
  <p>The unrecognized option was added by me, to remove the title bar. But after adding this option and restarting it, it fails to start.
      I thought this option might be located in "idea.vmoptions" file but could not find it there. Is there any other file where this option might be located? Or is there any way to start IntelliJ ignoring this error?</p>
