我正在编写一个小程序，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。
我正在使用以下代码来创建小程序(在
元素中创建)，并且在 FF 下(甚至在 XP 32 位上运行时的 Chrome)它运行良好:<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，在获取 JAR 文件之前尝试获取 cookie 时似乎会死锁。这是日志(包括堆栈转储):

Done.
查看堆栈转储，我的猜测是它试图在获取 applet jar(与 HTTP 请求一起发送)之前获取 cookie，但 getCookie() 调用挂起。
我在网上搜索过任何可能遇到过这个问题的人，但没有找到任何东西。
有没有人看过这个？如果是这样 - 是否有解决方法？
注意:发生这种情况时，Chrome 页面变得完全没有响应，并且我收到“Kill Page”提示。
这发生在 JRE 1.6.0.29 或 1.7.0.1
更新:我忘了说，如果我在本地服务器上测试它(Apache 在我的开发机器上的 VirtualBox 中的 Linux 上运行)，我不会遇到任何问题。
最佳答案
看看你的转储，我认为你没有遇到死锁(至少在线程级别没有)，你的主线程似乎在无休止地等待消息:
"main" prio=6 tid=0x0024dc00 nid=0x530 in Object.wait() [0x0039f000]
java.lang.Thread.State: WAITING (on object monitor)
at java.lang.Object.wait(Native Method)
- waiting on <0x298c7c10> (a sun.plugin2.message.Queue)
...
通过谷歌搜索我发现了这个问题:

有关使用 LiveConnect(小程序和浏览器的 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)或者您的问题是否由此问题引起。
另一个提示可能是此链接(挂起特定于 chrome):

关于使用 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，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/7885715/
