Where are fonts defined/installed for Openjdk Java on linux

Installed Oracle 8 jdk on Ubuntu, within jre/lib it has various fontProperties files plus a fonts dir containing fonts. But when installed OpenJdk 8 there is no such fonts folder on font files within jre/lib.

So where does it get its fonts from, does it come with any fonts on depen on the system having some fonts installed somewhere else.

Update Based on advise from gerynix

fc-list

returns no fonts

GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailableFontFamilyNames()

gives

java.lang.NullPointerException

It gets it from the environment on top of which you are running your application.

Look into:

GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailableFontFamilyNames()
