在Ubuntu上安装了Oracle 8 jdk，在jre/lib中它具有各种fontProperties文件和一个包含字体的字体目录。但是，当安装OpenJdk 8时，jre/lib中的字体文件上没有这样的字体文件夹。在Linux上为Openjdk Java定义/安装字体的位置

那么它从哪里得到它的字体，它是否与任何字体一起取决于系统在其他地方安装了一些字体。

更新 根据通知发出gerynix

fc-list

没有返回字体

GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailableFontFamilyNames()

给
