java - Richfaces fileuploader nullpointer firefox

问题描述

随着 Firefox 62 的引入，我现有的 RichFaces 文件上传器在尝试解码上传的文件时突然抛出空指针。这是在 JBoss 5.1 环境中使用 Richfaces 3.3.3。我试过上传不同的图像类型无济于事。还需要注意的是，这个问题只发生在 Firefox 62 上，以后所有其他浏览器都可以正常工作。

堆栈跟踪：

文件上传器 xhtml：

<a4j:support  event="onsizerejected" action="#{manageAttachmentContentItemAction.onFileSizeRejected}" reRender="uploadFunction"  />

任何提示将不胜感激

解决方案

有一个解决这个问题的方法，我们可以通过 try/catch 包围抛出这个异常的代码，一切都会正常工作。我已经尝试过了，它工作正常。
