On a Linux system with a black box, neither the system nor openjdk had fonts, so this caused a problem for my Java application.
To get around this, I copied the Lucida fonts from the Oracle Java installation to the jre/lib/fonts directory and ran fc-cache -rv jre/lib/fonts and it worked for me.
But it looks like these standard fonts do not support CKJ scripts, what is a font that I can copy into fonts that will add support for these scripts for my Java application.
Note. I cannot run installation or the like on a linux machine. I need a font that I can simply associate with my application, which I can then copy to the jre / lib / fonts folder.
