   Preondition Violations

   Type org.eclipse.swt.graphics.Image of variable rightGradient does not match with type org.eclipse.emf.ecore.resource.impl.ExtensibleURIConverterImpl.ContentHandlerList of variable contentHandlers
   - Make classes org.eclipse.swt.graphics.Image and org.eclipse.emf.ecore.resource.impl.ExtensibleURIConverterImpl.ContentHandlerList extend a common superclass

       if (contentHandlers == null)

   2 | contentHandlers = new ContentHandlerList();

   Preondition Violations
   Unmatched statement contentHandlers=new ContentHandlerList(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted

   Preondition Violations

   2 | Unmatched statement contentHandlers=new ContentHandlerList(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted
