我正在使用WSS4J创建一个带有来自密钥库的证书的soap请求签名者。我的密钥库格式是.pkcs，一切都适用于第一次签名，但是如果我尝试运行程序来签署多个文档，并且它没有在密钥库中找到证书。在我看来，证书可能在签名期间被消耗，这意味着它不再存在于当前环境中。如果程序停止并再次启动，它将签署第一个请求，但第二个请求失败。我已多次介入，无法弄清楚原因是什么。此代码是证书从密钥库this.certUri = getWsConfig().getIdAllocator().createSecureId("X509-", certs[0]);消失之前调用的最后一件事，这可以在WSSecSignature.class的第556行找到。这是我的代码。

另外，我想在WSSecBase.class中启用doDebug模式，但它不会在变量查看器中显示以切换值。我在构造函数中创建了一个断点，并将其设置为被监视，但它从未显示为切换。

使用最新WSS4J SNAPSHOT代码上的WSS4J测试源的.p12，您的测试用例可以正常工作。您使用的是旧版WSS4J吗？如果是这样，请尝试使用最新版本+看看它是否有效。如果没有，那么请使用.p12文件创建一个测试用例+在WSS4J JIRA中创建一个新问题：
