Buggy source:
private static String addRouteOsgiDependencies(ExportFileResource libResource,List<ProcessItem> itemToBeExport) throws IOException {
  IPath libPath=ResourcesPlugin.getWorkspace().getRoot().getProject(JavaUtils.JAVA_PROJECT_NAME).getLocation().append(JavaUtils.JAVA_LIB_DIRECTORY);
  String importPackages=null;
  for (  ProcessItem pi : itemToBeExport) {
    IOsgiDependenciesService dependenciesService=(IOsgiDependenciesService)GlobalServiceRegister.getDefault().getService(IOsgiDependenciesService.class);
    if (dependenciesService != null) {
      Map<String,String> bundleDependences=dependenciesService.getBundleDependences(pi,pi.getProperty().getAdditionalProperties());
      String externalLibs=bundleDependences.get(IOsgiDependenciesService.BUNDLE_CLASSPATH);
      String[] libs=externalLibs.split(IOsgiDependenciesService.ITEM_SEPARATOR);
      Set<URL> list=new HashSet<URL>();
      for (      String s : libs) {
        if (s.isEmpty()) {
          continue;
        }
        IPath path=libPath.append(s);
        URL url=path.toFile().toURI().toURL();
        list.add(url);
      }
      libResource.addResources(new ArrayList<URL>(list));
      importPackages=bundleDependences.get(IOsgiDependenciesService.IMPORT_PACKAGE);
    }
  }
  return importPackages;
}

Fixed version (ground truth):
