Java JCE无法在jarsplice创建的jar中验证提供者BC

我正在开发一款游戏,我正在使用Slick2D库.我也使用bouncycastle进行加密.然后我使用jarsplice将所有内容打包在一个漂亮的可执行文件中.它运行正常,直到它需要加密某些东西.它给了我一个java.lang.SecurityException: JCE cannot authenticate the provider BCAnd我正在使用一个签名的jar文件(http://www.bouncycastle.org/download/bcprov-jdk15on-150.jar)

这是堆栈跟踪

 java.lang.SecurityException: JCE cannot authenticate the provider BC

那么如何验证要运行的jar文件呢？这是一个独立的可执行jar文件.
