我对已签名的 Java 小程序有疑问 - 具体来说，为什么没有使用我的证书对其进行签名。我在 Eclipse 中使用 Maven。
小程序 (a) 允许用户选择本地文件或目录，(b) 加密文件，以及 (c) 将文件上传到基于 PHP 的网页。可能使用我的证书对小程序进行签名 - 即，通过 Maven 代码，使用 maven-jar 插件。例如：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<executions>
签名
//images/src/main/resources/META-INF/MANIFEST.MF false
[
PATH_TO_MY_KEYSTORE] [MY ALIAS] [******] [******] [PATH_TO_SIGNED_JAR] true true
（显然我已经掩盖了其中的一些，因为我为偏执狂的 git 工作！）一切都很好地打包，小程序加载到页面中；但是，有两件事很麻烦：（1）当小程序加载时，它将充气城堡军团识别为用于签署小程序的证书；（2）当小程序使用 JFileChooser 可以访问文件系统时，“访问拒绝”权限 - 文件 - 在尝试执行上面的 (c) 时抛出，将文件发送到网站。（我使用 Apache HTTP 组件来执行此操作。）
我的小程序与依赖 jar 分开打包 - 包括 Bouncy Castle jar。
我的问题是：为什么 BC 是我的小程序的签名者，而不是我自己的证书，如上所述？这是一个Maven问题吗？当然，在开发中，一切正常，因为 Eclipse 为 Applet Viewer 编写了策略文件。
这是 Eclipse 中的输出片段 - 看起来一切都应该是 honky-dory：

任何帮助将不胜感激。谢谢。顺便说一下，这是堆栈跟踪：
