java - ApachePoi 在 OpenJdk 1.8.0_121 上因字体错误而失败 在 Oracle Jre 上没问题

Question

错误发生在初始化 org.apache.poi.ss.usermodel.Sheet 期间我可以修复此问题以防止 Linux 上的 OpenJdk 出现故障吗？

根据评论，在 lib 中找不到字体文件

Answer 1

为了完整起见，我在这里添加 Paul Taylor 的回答:

Openjdk depends on system fonts of which i had none installed, but I found that creating a fonts folder in the jre's lib folder and just copyig some fonts into it fixed the problem
