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.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/wizards/buildpaths/SourceContainerWorkbookPage.java
modifiedEntries.add(curr);
				}
			}
		}
	}
			
	private CPListElement[] openSourceContainerDialog(CPListElement existing) {
		
		Class[] acceptedClasses= new Class[] { IProject.class, IFolder.class };
		TypedElementSelectionValidator validator= new TypedElementSelectionValidator(acceptedClasses, existing == null, getExistingContainers(null));
		
		IProject[] allProjects= fWorkspaceRoot.getProjects();
		ArrayList rejectedElements= new ArrayList(allProjects.length);
		IProject currProject= fCurrJProject.getProject();
		for (int i= 0; i < allProjects.length; i++) {
			if (!allProjects[i].equals(currProject)) {
				rejectedElements.add(allProjects[i]);
			}
		}
		ViewerFilter filter= new TypedViewerFilter(acceptedClasses, rejectedElements.toArray());
		
		ILabelProvider lp= new WorkbenchLabelProvider();
		ITreeContentProvider cp= new WorkbenchContentProvider();
		String title= (existing == null) ? NewWizardMessages.getString("SourceContainerWorkbookPage.ExistingSourceFolderDialog.new.title") : NewWizardMessages.getString("SourceContainerWorkbookPage.ExistingSourceFolderDialog.edit.title"); 
		String message= (existing == null) ? NewWizardMessages.getString("SourceContainerWorkbookPage.ExistingSourceFolderDialog.new.description") : NewWizardMessages.getString("SourceContainerWorkbookPage.ExistingSourceFolderDialog.edit.description"); 
		FolderSelectionDialog dialog= new FolderSelectionDialog(getShell(), lp, cp);
		dialog.setValidator(validator);
		dialog.setTitle(title);
		dialog.setMessage(message);
		dialog.addFilter(filter);
