我需要从Java调用一个安全的WCF服务，并使用双向认证。所有东西都运行良好，除了我无法发送大于48680字节大小的消息。因此，成功发送了48680字节的消息，但是48681字节的消息没有发送成功，Java应用程序会出现读取超时异常，尽管WCF的配额设置允许发送更大的消息。
那么问题可能是什么？
编辑 源代码如下：

我已经使用 .net WCF 客户端测试了该服务，并成功调用了该服务，所以我想知道问题出在哪里？为什么 WCF 客户端可以调用该服务，而即使使用普通的 HTTP POST 请求和 UrlConnection 的 Java 客户端却不能呢？

这是一份 SOAP 消息样例：
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<DoSomethingUseful xmlns="http://namespace/2012/01/service">
...
</DoSomethingUseful>
</soap:Body>
</soap:Envelope>

我被告知在 .net 服务端会出现 "需要客户端证书。请求中未找到证书" 的信息，似乎是在 ssl 会话恢复时发生的。当 Content-Length 大于 48680 字节时才会出现该情况。 此外，WCF 服务配置了基本的 Http 绑定来使用传输层安全性。
