title: NetBeans 12.0, Java 8, autocomplete/code assistance completely stopped working
body: <p>Autocomplete isn't working in my NetBeans IDE. It's a fresh installation, didn't change any settings. Reinstalled a couple of times. Not sure what I did to break it.</p>
  <p>Java version is assigned in the settings and it does compile and run Java programs.</p>
  <p>I have the following installed:</p>
  <ul>
  <li>NetBeans IDE 12.0</li>
  <li>Java 8 Update 271</li>
  <li>Java 8 Update 271 (64-bit) Java</li>
  <li>SE Development Kit 8 Update 191 (64-bit)</li>
  </ul>
  <p>Does anyone have an idea what it could be?</p>
