Good afternoon,
I launched the Oracle Database 12c runInstaller, on a CentOS7 server, and I can't read any text :

I tried to "export _JAVA_OPTIONS='-Dawt.useSystemAAFontSettings=lcd'" as proposed in Rendering of GUI x11 . After that I see "Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=lcd" when the GUI starts, but no change, the texts are the same.
Does someone know what can cause this ?
I tested the installer on my Ubuntu workstation (same zip file), it works :

Regards,
Jean Coiron
