title: How do I debug the Eclipse Plugin error "Plugin was unable to load class"?
body: <p>It is trying to load my TabGroup from the Debug Dialog but I get the error that it is unable to load my tab group class.</p>
  
  <p>In the "details" of the error all it says is:</p>
  
  <p>"org/eclipse/debug/ui/AbstractLaunchConfigurationTabGroup"</p>
  
  <p>Which is the class that my TabGroup extends.</p>
