title: How to find a class in java 12's html javadoc, now that class index is removed?
body: <p>I just upgraded JAVA + Javadoc to version 12.
  Now, Javadoc has totally been 'restructured' into modules.
  Example: searching for the description of 'JComboBox',
  I couldn't find it: there's no more class index added.
  Finally I searched on disk for a file 'JComboBox.html', but that feels clumsy.</p>
  
  <p>Is there another way to find a class description in the new Javadoc?</p>
