public class CompositeRefactoringProcessor
extends AbstractRenameProcessor

This class aggregates all processors of the participants to the same JDT refactoring and combines their changes. Unfortunately, JDT loads the same refactoring participants multiple times for the same refactoring processor (for different refactoring modifications). OTOH we have to combine the changes of the multiple participant calls in order to avoid collisions. We solve this with a singleton CompositeRefactoringProcessor.Access class, that keeps track of the ongoing JDT refactoring.
