Bug 178297 [Dialogs] - remove required field color
There are still some dialogs using the (now deprecated) class FieldAssistColors. We shouldn't color the required fields anymore in these dialogs: NewFolderDialog CreateLinkedResourceGroup ResourceWorkingSetPage ContainerSelectionGroup ResourceAndContainerGroup
bundles/org.eclipse.ui.ide/extensions/org/eclipse/ui/dialogs/NewFolderDialog.java
folderNameField = new Text(folderGroup, SWT.BORDER);
		GridData data = new GridData(GridData.FILL_HORIZONTAL);
		data.widthHint = IDialogConstants.ENTRY_FIELD_WIDTH;
		folderNameField.setLayoutData(data);
		folderNameField.setFont(font);
		folderNameField.addListener(SWT.Modify, new Listener() {
			public void handleEvent(Event event) {
				validateLinkedResource();
			}
		});
		folderNameField.setBackground(FieldAssistColors
				.getRequiredFieldBackgroundColor(folderNameField));
	}
