Bug description:
  Binary package hint: unity

  On launcher, all Java Swing applications are with wrong name. Their
  tooltip shows the Java class name, with the dots changed by hiphens.

  For example, Netbeans icon itself gets inactive after startup.
  Then an icon with a '?' shows up indicating "java-lang-Thread" on mouseover.

  Treviño: this issue is java related (affecting javaws apps as well) and it's caused by the fact that the Java apps doesn't  correctly set the WM_CLASS X property on their windows. There was a bug for it (including a patch): http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6528430
  The ubuntu java package should probably include it.

  A workaround to fix it is to use this window matching agent: https://github.com/jelmerk/window-matching-agent then you need to update the application
  .desktop file to change the Exec value including -javaagent:agent.jar=<AppWMClass> and adding StartupWMClass=<AppWMClass>.
