org.apache.myfaces.trinidadinternal.ui.RootRenderingContext.getRendererManager 处出现 NullPointerException

Question

我正在使用 IBM WAS 7.0 和 myfaces.version 1.1.5，但是当我运行该应用程序时，会触发以下错误。但相同的代码在其他环境（具有相同配置的环境）中运行良好。

当启用安全性并禁用供应时，WAS 7 上可能会发生

java.lang.NullPointerException，您可以应用修订包 8.0.0.11 和 8.5.5.7，请参阅 (https://www-01.ibm.com/support/ docview.wss?uid=swg1PI39369）了解更多详情
