Bug 34040 It takes a minute to expand a project in Package explorer
Build: RC1 For scalability testing, I'm developing against WSADIE. I imported a plug-in whose classpath contains >200 external jar entries. The project is initially collpsed. In the package explorer view, if you click on the + to expand the project, it will take about 60 seconds for the project to expand. After it expanded, I went into the view filters and changed it so that I could see the hidden '.*' files, it will take another minute to update the view.

postRunnable(new Runnable() {
				public void run() {
					Control ctrl= fViewer.getControl();
					if (ctrl != null && !ctrl.isDisposed()) {
						
						
						if (fViewer.testFindItem(addedElement) != null)
							fViewer.setSelection(selection);
					}
				}
			});	
		}

	private IJavaElement findAddedElement(IJavaElementDelta delta) {
		if (delta.getKind() == IJavaElementDelta.ADDED)  
			return delta.getElement();
		
		IJavaElementDelta[] affectedChildren= delta.getAffectedChildren();
		for (int i= 0; i < affectedChildren.length; i++) 
			return findAddedElement(affectedChildren[i]);
			
		return null;
	}
