Buggy source:
private ResourceBundle getComponentResourceBundle(IComponent currentComp,String source,AbstractComponentsProvider provider){
  try {
    AbstractComponentsProvider currentProvider=provider;
    if (currentProvider == null) {
      ComponentsProviderManager componentsProviderManager=ComponentsProviderManager.getInstance();
      for (      AbstractComponentsProvider curProvider : componentsProviderManager.getProviders()) {
        String path=new Path(curProvider.getInstallationFolder().toString()).toPortableString();
        if (source.startsWith(path)) {
          currentProvider=curProvider;
          break;
        }
      }
    }
    String installPath=currentProvider.getInstallationFolder().toString();
    String label=ComponentFilesNaming.getInstance().getBundleName(currentComp.getName(),installPath.substring(installPath.lastIndexOf(IComponentsFactory.COMPONENTS_INNER_FOLDER)));
    if (currentProvider.isUseLocalProvider()) {
      ResourceBundle bundle=null;
      IBrandingService brandingService=(IBrandingService)GlobalServiceRegister.getDefault().getService(IBrandingService.class);
      if (brandingService.isPoweredOnlyCamel()) {

        bundle=service.getResourceBundle(label);
      }
      return bundle;
    }
 else {
      ResourceBundle bundle=ResourceBundle.getBundle(label,Locale.getDefault(),new ResClassLoader(currentProvider.getClass().getClassLoader()));
      return bundle;
    }
  }

    ExceptionHandler.process(e);

Fixed version (ground truth):
private ResourceBundle getComponentResourceBundle(IComponent currentComp,String source,AbstractComponentsProvider provider){
  try {
    AbstractComponentsProvider currentProvider=provider;
    if (currentProvider == null) {
      ComponentsProviderManager componentsProviderManager=ComponentsProviderManager.getInstance();
      ArrayList<AbstractComponentsProvider> providers=componentsProviderManager.getProviders();
      for (      AbstractComponentsProvider curProvider : providers) {
        String path=new Path(curProvider.getInstallationFolder().toString()).toPortableString();
        if (source.startsWith(path)) {
          currentProvider=curProvider;
          break;
        }
      }
    }
    String installPath=currentProvider.getInstallationFolder().toString();
    String label=ComponentFilesNaming.getInstance().getBundleName(currentComp.getName(),installPath.substring(installPath.lastIndexOf(IComponentsFactory.COMPONENTS_INNER_FOLDER)));
    if (currentProvider.isUseLocalProvider()) {
      ResourceBundle bundle=null;
      IBrandingService brandingService=(IBrandingService)GlobalServiceRegister.getDefault().getService(IBrandingService.class);
      if (brandingService.isPoweredOnlyCamel()) {
        bundle=currentProvider.getResourceBundle(label);
      }
 else {
        ITisLocalProviderService service=(ITisLocalProviderService)GlobalServiceRegister.getDefault().getService(ITisLocalProviderService.class);
        bundle=service.getResourceBundle(label);
      }
      return bundle;
    }
 else {
      ResourceBundle bundle=ResourceBundle.getBundle(label,Locale.getDefault(),new ResClassLoader(currentProvider.getClass().getClassLoader()));
