Fixed version (ground truth):

      if (modules != null && modules.length == 1) {
        IModule[] add=null;
        if (!ServerUtil.containsModule(server,modules[0],monitor)) {
          add=new IModule[]{modules[0]};
        }
 else {
          IServerWorkingCopy wc=server.createWorkingCopy();
          wc.modifyModules(null,modules,monitor);
          wc.save(true,null);
