我们正在尝试升级到 Crystal Report for Eclipse 的 SP24，但发现我们的一些报告在生成报告时失败并出现 NullPointerException。我在下面包含了堆栈跟踪 - 有人知道可能出了什么问题或有任何解决方法吗？

以防万一其他人在这里遇到同样的问题。

问题是：较新的 JDK 版本未附带 Crystal Report 引擎所期望的 lib/fonts 文件夹。

一个有点不满意但可行的解决方案是：

  1. 创建一个字体文件夹 -> %JAVA_HOME%/lib/fonts
  2. 将字体从“Windows\Fonts”复制到 %JAVA_HOME%/lib/fonts。

那么问题应该就解决了。
