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/CPListElement.java
}
				javaDocLocation= JavaUI.getLibraryJavadocLocation(path);
				break;
			case IClasspathEntry.CPE_SOURCE:
				res= root.findMember(path);
				if (res == null) {
					if (root.getWorkspace().validatePath(path.toString(), IResource.FOLDER).isOK()) {
						res= root.getFolder(path);
					}
					isMissing= true;
				}
				break;
			case IClasspathEntry.CPE_PROJECT:
				res= root.findMember(path);
				isMissing= (res == null);
				break;
		}
		CPListElement elem= new CPListElement(project, curr.getEntryKind(), path, res);
		elem.setExported(curr.isExported());
		elem.setAttribute(SOURCEATTACHMENT, curr.getSourceAttachmentPath());
		elem.setAttribute(JAVADOC, javaDocLocation);
		elem.setAttribute(OUTPUT, curr.getOutputLocation());
		elem.setAttribute(EXCLUSION, curr.getExclusionPatterns()); 
		if (project.exists()) {
			elem.setIsMissing(isMissing);
		}
		return elem;
