Bug 41523 Keep Order of libs when editing library [build path]
When I edit a library in the Properties dialog of my project using "Properties"->"Java Build Path"->"Libraries"->"Edit", e.g. changing the JRE from 1.4 to 1.3, or changing from an old version of a JAR to a newer one, the changed library is at the last position in the classpath. It should kept at the position it was.

			res= openNewSourceContainerDialog(elem);
		}
		
		if (res != null) {
			fFoldersList.replaceElement(elem, res);
		}
	}
	private void editAttributeEntry(CPListElementAttribute elem) {
		String key= elem.getKey();
		if (key.equals(CPListElement.OUTPUT)) {
			CPListElement selElement=  elem.getParent();
			OutputLocationDialog dialog= new OutputLocationDialog(getShell(), selElement);
			if (dialog.open() == Window.OK) {
				selElement.setAttribute(CPListElement.OUTPUT, dialog.getOutputLocation());
				fFoldersList.refresh();
				fClassPathList.dialogFieldChanged(); 
			}
		} else if (key.equals(CPListElement.EXCLUSION)) {
			CPListElement selElement= elem.getParent();
			ExclusionPatternDialog dialog= new ExclusionPatternDialog(getShell(), selElement);
			if (dialog.open() == Window.OK) {
				selElement.setAttribute(CPListElement.EXCLUSION, dialog.getExclusionPattern());
				fFoldersList.refresh();
				fClassPathList.dialogFieldChanged(); 
			}
