我们有一个基于JNLP的webstart应用程序，它正在推出并与JRE 1.6,1.7 32位＆amp; 64位版本（操作系统：Windows 7企业版64位和应用程序服务器：Websphere 8.5.5）。关于JRE 1.8，应用程序使用64位JRE正常启动但未能使用32位JRE启动。 使用32位1.8 JRE，我们得到一个异常，即虽然Groovy 2.3.9 jar中存在特定类，但找不到其中一个groovy类。我还通过Java Cacher Viewer确认，当我们启动初始JNLP时，Groovy-all.jar成功下载到用户缓存文件夹（c：\ Users {userid} \ AppData \ LocalLow \ Sun \ Java）
以下是我们获得的异常的完整跟踪
