Bug 34335 DND doesn't work
RC2 Linux-GTK Drag and drop doesn't work. I've tried it in the DNDExample and in the package explorer and drags are never initiated.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/packageview/PackageExplorerPart.java
IStructuredSelection is= (IStructuredSelection)invalidSelection;
				List ns= null;
				if (newSelection instanceof IStructuredSelection) {
					ns= new ArrayList(((IStructuredSelection)newSelection).toList());
				} else {
					ns= new ArrayList();
				}
				boolean changed= false;
				for (Iterator iter= is.iterator(); iter.hasNext();) {
					Object element= iter.next();
					if (element instanceof IJavaProject) {
						IProject project= ((IJavaProject)element).getProject();
						if (!project.isOpen()) {
							ns.add(project);
							changed= true;
						}
					} else if (element instanceof IProject) {
						IProject project= (IProject)element;
						if (project.isOpen()) {
							IJavaProject jProject= JavaCore.create(project);
							if (jProject != null && jProject.exists())
								ns.add(jProject);
								changed= true;
						}
					}
				}
				if (changed) {
					newSelection= new StructuredSelection(ns);
					setSelection(newSelection);
				}
