Bug 24421 Better UI feedback when class path entries are missing [icons]
Build 2.1.M1. I get a nice message at the top of the Project/Properties/Java Build Path when I have missing entries on my HD from what I have specified on the class path: "Class path entries are missing." BUT the dialog provides no feedback as to which ones are missing, which can be a burden to figure out if you have a long class path in the list. I would like to suggest having the list entry displayed in RED when a class path entry is missing. That would make it easy to spot. Red is pretty universal for "something is wrong" or "stop". Thank you for considering this request, Gary

dialog.setTitle(NewWizardMessages.getString("BuildPathsBlock.ChooseOutputFolderDialog.title"));

		dialog.setMessage(NewWizardMessages.getString("BuildPathsBlock.ChooseOutputFolderDialog.description")); 
		dialog.addFilter(filter);
		dialog.setInput(fWorkspaceRoot);
		dialog.setInitialSelection(initSelection);
		
		if (dialog.open() == ElementTreeSelectionDialog.OK) {
			return (IContainer)dialog.getFirstResult();
		}
		return null;

			TabItem tabItem= (TabItem) widget;
			BuildPathBasePage newPage= (BuildPathBasePage) tabItem.getData();
			if (fCurrPage != null) {
				List selection= fCurrPage.getSelection();
				if (!selection.isEmpty()) {
					newPage.setSelection(selection);
				}
			}
			fCurrPage= newPage;
			fPageIndex= tabItem.getParent().getSelectionIndex();
