Fixed version (ground truth):

        String path=new Path(curProvider.getInstallationFolder().toString()).toPortableString();
        if (source.startsWith(path)) {
          if (cachedPathSource != null) {
            if (path.contains(cachedPathSource)) {
              currentProvider=curProvider;
              break;
            }
          }
 else {
            currentProvider=curProvider;
