从 Java 7u21 开始，我在自己制作的 JavaFX 小程序中偶然发现了一些奇怪的行为。

在服务器端，我有一个 Glassfish 3 服务器和一个 mysql 数据库。在客户端，我使用 Jersey 通过向我的 Glassfish 服务器发送请求来从数据库中获取数据。当我通过 JAR 文件启动程序时一切正常，但是当我通过 JNLP 文件启动它时，我注意到自 7u21 以来的一些奇怪行为。让我尝试向您展示：

我做了一个简单的请求，它应该给出一个 XML 响应：

方法（客户端）：

public List<Users> getUsersHierarchyTreeFilteredByUserlevel(int id, int betweenStart, int betweenEnd) throws UniformInterfaceException {
    WebResource resource = webResource;
    resource = resource.path(java.text.MessageFormat.format("users/{0}/hierarchy", String.valueOf(id))).queryParam("start", "" + String.valueOf(betweenStart)).queryParam("end", "" + String.valueOf(betweenEnd));
    System.out.println(resource.getURI());
    return resource.accept(javax.ws.rs.core.MediaType.APPLICATION_XML).get(new GenericType<List<Users>>() {});
}

URI：System.out.println(resource.getURI());

http://localhost:8080/myWS/webresources/entities.users/users/4/hierarchy?start=5&end=5

Java 控制台：

network: Cache entry not found [url: http://localhost:8080/myWS/webresources/entities.users/users/4/hierarchy?start=5&end=5, version: null]
network: Connecting http://localhost:8080/myWS/webresources/entities.users/users/4/hierarchy?start=5&end=5 with proxy=DIRECT

cache: Adding MemoryCache entry: http://localhost:8080/myWS/webresources/entities.users/users/4/hierarchy
java.io.IOException: stream is closed

如您所见，我收到了一个 IOException。这似乎发生在getUsersHierarchyTreeFilteredByUserlevel (...)方法中的resource.accept(...)处。但是，当我将 URI 粘贴到浏览器中时，它会显示正确的 XML 数据吗？我不知道为什么......它在运行 JAR 本身或使用 7u17 时有效。

有任何想法吗？提前致谢！

It all had to do with the same issues regarding this question:

Authentication required window popping up after 7u21 update

and follow up question:

basic authentication fails with glassfish
