我正在使用 domino appdev pack 1.0.7 Java API 来从数据库中读取文档。目前仅尝试 Domino AppDev Pack 中的示例代码。这是代码：
Server server = new Server('testappdev.com.tw', 5000,
new File("ca.crt"),
new File("user.crt"),
new File("user.key"),
"",
"",
Executors.newSingleThreadExecutor());
Database client = server.useDatabase("test.nsf");
String query = "'Contact' and FirstName = 'fname'";
List<Document> responseDocs = client.readDocuments(query).get();
当查询有结果文档时它工作正常，但是当查询没有结果文档时它在下面出现异常。

查询没有结果文档时如何防止此错误？
谢谢！
