使用 JRE 1.6.0.29 或 1.7.0.1 的 Win 7 64 上的 Chrome 上的 Java 小程序死锁

Question

我正在编写一个小程序，当在 Windows 7 64 上的 Chrome (14.0.835.202 m) 下运行时，它有时甚至在进入 init() 之前就挂起。

我使用以下代码来创建小程序（在 元素），并且在 FF 下（甚至在 XP 32 位上运行时的 Chrome）运行良好：

<script type="text/javascript">
var attributes = {
    id: 'JavaUploader',
    code: 'com.foo.Uploader.class',
    archive: '/java/uploader_0.0.4.jar',
    width: 1,
    height: 1,
};
var parameters = {};
var version = '1.6';
deployJava.runApplet(attributes, parameters, version);
</script>

当它挂起时，在尝试获取 cookie 之前似乎会陷入僵局获取 JAR 文件。这是日志（包括堆栈转储）：

查看堆栈转储，我的猜测是它试图在获取 applet jar 之前获取 cookie（与 HTTP 请求一起发送），但 getCookie() 调用挂起。

我在网上搜索了可能遇到此问题的其他人，但没有找到任何信息。

还有其他人看过这个吗？如果是这样 - 有解决方法吗？

注意：发生这种情况时，Chrome 页面将完全无响应，并且我会收到“终止页面”提示。

JRE 1.6.0.29 或 1.7.0.1 都会发生这种情况

更新： 我忘了提及，如果我在本地服务器上测试它（Apache 在我的开发计算机上的 VirtualBox 中的 Linux 上运行），我不会遇到任何问题。

Answer 1

看看你的转储，我不认为你遇到了死锁（至少不是在线程级别），你的主线程似乎无休止地等待消息：

"main" prio=6 tid=0x0024dc00 nid=0x530 in Object.wait() [0x0039f000]
   java.lang.Thread.State: WAITING (on object monitor)

...

谷歌搜索一下这个问题我发现了这个：

https://bugs.java.com/bugdatabase/view_bug?bug_id=6668033

有关使用 LiveConnect（小程序和浏览器 JavaScript 引擎之间的桥梁）的错误。我会尝试关闭 javascript 并查看小程序是否仍然挂起（然后是其他问题）或者您的问题是否是由此问题引起的。

另一个提示可能是此链接（特定于 chrome 的挂起）：

https://github.com/CoderLine /alphaTab/issues/17

以及提到的可能的解决方法。

Answer 2

这是您问题的解决方案。调用 myApplet.somefunc();当您的小程序实际启动后。

Answer 3

我遇到了类似的问题，我使用 部署小程序示例解决了它。
另外我必须修改deployJava.js的源代码，因为document.write函数刷新了页面。我将其替换为 $('body').append。
之后，chrome 开始表现得很奇怪 - 它创建并运行小程序两次，我可以与第二个实例通信，因为它总是挂起。使用

setTimeout(function() {
    myApplet.someFunction();
}, 0);

解决了这个问题。
我的整个部署脚本：

var baseurl = location.protocol + "//" + location.host + Form.fields.baseUrl;
var attributes = {
    id: 'myApplet',
    code: 'main.java.myApplet.class',
    archive: baseurl + 'Applet/appletJar.jar',
    width: 100,
    height: 100
};
deployJava.runApplet(attributes, {}, '1.7');

setTimeout(function () {
    if (myApplet !== undefined && "somefunc" in myApplet) {
        myApplet.somefunc();
    }
}, 0);
