workaround is to run code in a new thread, but thats a bad solution:

Thread thread = new Thread() {
   public void run() {
      RunAsWork<Object> raw = new RunAsWork<Object>() {
         public Object doWork() throws Exception {
            List<NodeRef> list = BehaviorBugWebScript.getTargetAssoc(nodeRef, BehaviorBugWebScript.TEST_ASSOC);
            for (NodeRef node : list) {
               nodeService.deleteNode(node);
            }
         }
      };
      AuthenticationUtil.runAs(raw, AuthenticationUtil.getAdminUserName());
   }
};
thread.start();
