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/LibrariesWorkbookPage.java
} else {
			title= NewWizardMessages.getString("LibrariesWorkbookPage.ContainerDialog.edit.title"); 
			elem= existing.getClasspathEntry();
		}
		return openContainerDialog(title, new ClasspathContainerWizard(elem, fCurrJProject, getRawClasspath()));
	}
	
	private CPListElement[] openContainerDialog(String title, ClasspathContainerWizard wizard) {
		wizard.setWindowTitle(title);
		WizardDialog dialog= new WizardDialog(getShell(), wizard);
		PixelConverter converter= new PixelConverter(getShell());
		
		dialog.setMinimumPageSize(converter.convertWidthInCharsToPixels(40), converter.convertHeightInCharsToPixels(20));
		dialog.create();
		if (dialog.open() == Window.OK) {
			IClasspathEntry created= wizard.getNewEntry();
			if (created != null) {			
				CPListElement elem= new CPListElement(fCurrJProject, IClasspathEntry.CPE_CONTAINER, created.getPath(), null);
				if (elem != null) {
					return new CPListElement[] { elem };
				}
			}
		}			
		return null;
	}

		if (elem.getEntryKind() == IClasspathEntry.CPE_CONTAINER) {
			return null;
