当我的应用程序尝试从 JAVA 加载 RSA 算法提供程序类时，我遇到错误。异常堆栈如下：

我用 google 搜索了错误消息，大多数帖子都说这是因为 JVM 找不到 sunjce_provider.jar。但是，我可以在 /Library/Java/Home/lib/ext 文件夹中找到该文件。
平台是Mac OS X 10.6，Java版本是1.6.0_17。
我的问题是：
- 为什么 JVM 不搜索 /Library/Java/Home/lib/ext 来查找 jar 文件？
- 我们可以通过修改任何配置文件来更改 CLASSPATH 或 java.ext.dirs 属性吗？
- 有什么建议来解决这个问题吗？
提前致谢。
在 Mac 上升级到新的 Java 版本后，我遇到了同样的问题。
我的 (maven) 项目从命令行运行正常，但在 Eclipse 中出现“SunTlsRsaPremasterSecret”错误。
解决方案是删除 Eclipse 配置中已安装的 JRE，然后再次添加它们（使用“搜索...”按钮）。
