Mac上的java和签名JAR

我有一个作为jnlp启动的胖Java客户机。罐子都签了名

此应用程序适用于除Mac OSX 10.5.8之外的所有操作系统

使用Safari或FireFox，当我启动应用程序时，会出现以下错误：

java.lang.NullPointerException

这是本机上的浏览器设置功能还是Java配置功能？ 正如我所说，JAR在除此操作系统/机器之外的所有其他操作系统/平台上都经过签名和验证

关于这方面的任何想法

这与我们有一些可疑的相似之处（OS X、签名JAR、安全故障）和一些不同之处（自签名与纯粹基于OS版本的以及OS X的不同版本）。它是使用自签名证书还是“真实”代码签名证书签名的？
