Buggy source:
private boolean isAnyComponentMissing() throws IOException {
  Iterator it=ComponentManager.getInstance().getComponentEntryMap().entrySet().iterator();
  List<String> componentsList=new ArrayList<String>();
  while (it.hasNext()) {
    Map.Entry<String,ComponentInfo> entry=(Map.Entry<String,ComponentInfo>)it.next();
    componentsList.add(entry.getKey());
  }
  ECodeLanguage currentLanguage=LanguageManager.getCurrentLanguage();
  ComponentsProviderManager componentsProviderManager=ComponentsProviderManager.getInstance();
  for (  AbstractComponentsProvider componentsProvider : componentsProviderManager.getProviders()) {
    if (componentsProvider.getInstallationFolder().exists()) {
      File source=componentsProvider.getInstallationFolder();
      File[] childDirectories;
      FileFilter fileFilter=new FileFilter(){
        public boolean accept(        final File file){
          return file.isDirectory() && file.getName().charAt(0) != '.' && !file.getName().equals(IComponentsFactory.EXTERNAL_COMPONENTS_INNER_FOLDER) && isComponentVisible(file.getName());
        }
      }
;
      if (source == null) {
        continue;
      }
      childDirectories=source.listFiles(fileFilter);
      for (      File component : childDirectories) {
        if (!componentsList.contains(component.getName())) {
          String mainXmlFileName=ComponentFilesNaming.getInstance().getMainXMLFileName(component.getName(),currentLanguage.getName());
          File mainXmlFile=new File(component,mainXmlFileName);
          if (mainXmlFile.exists()) {

        }

Fixed version (ground truth):
private boolean isAnyComponentMissing() throws IOException {
  Iterator it=ComponentManager.getInstance().getComponentEntryMap().entrySet().iterator();
  List<String> componentsList=new ArrayList<String>();
  while (it.hasNext()) {
    Map.Entry<String,ComponentInfo> entry=(Map.Entry<String,ComponentInfo>)it.next();
    componentsList.add(entry.getKey());
  }
  ECodeLanguage currentLanguage=LanguageManager.getCurrentLanguage();
  ComponentsProviderManager componentsProviderManager=ComponentsProviderManager.getInstance();
  for (  AbstractComponentsProvider componentsProvider : componentsProviderManager.getProviders()) {
    if (componentsProvider.getInstallationFolder().exists()) {
      File source=componentsProvider.getInstallationFolder();
      File[] childDirectories;
      FileFilter fileFilter=new FileFilter(){
        @Override public boolean accept(        final File file){
          return file.isDirectory() && file.getName().charAt(0) != '.' && !file.getName().equals(IComponentsFactory.EXTERNAL_COMPONENTS_INNER_FOLDER) && isComponentVisible(file.getName());
        }
      }
;
      if (source == null) {
        continue;
      }
      childDirectories=source.listFiles(fileFilter);
      for (      File component : childDirectories) {
        if (!componentsList.contains(component.getName())) {
          String mainXmlFileName=ComponentFilesNaming.getInstance().getMainXMLFileName(component.getName(),currentLanguage.getName());
          File mainXmlFile=new File(component,mainXmlFileName);
          if (mainXmlFile.exists()) {
            return true;
          }
