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.

private final Object[] EMPTY_ARR= new Object[0];
		
		
		public void customButtonPressed(TreeListDialogField field, int index) {
			sourcePageCustomButtonPressed(field, index);
