Hi, I'm currently investigating a problem where openjfx is not using FontConfig on a CentOS machine.
Error message: ... Loading FontFactory com.sun.javafx.font.freetype.FTFactory Subpixel: enabled Freetype2 Loaded (version 2.8.0) LCD support Disabled Fallback fontDir is /root/jdk-11.0.5+10/lib/fonts exists = false java.io.FileNotFoundException: null/allfonts.properties (No such file or directory) Fall back to opening the files *** FONTCONFIG LOCATED FONTS: Not using FontConfig Fontconfig returned no font for sans:regular:roman ... I'm using openjfx bundled with my application in a fat jar. (dependencies javafx-base, javafx-web, javafx-swing) (Tested openjfx versions: 11, 11.0.1, 13, 13.0.1) The jar is working without any problems on two different machines, one with a fresh installation of CentOS 7.4 with Gnome. On other existing machines (CentOS 7.4) i see the error above, terminating with jvm core dump due to no available fonts. I tested the behaviour with two jdk distributions from adoptopenjdk (OpenJDK11U-jdk_x64_linux_hotspot_11.0.5_10) and Bellsoft (bellsoft-jdk11.0.5+11). FontConfig seem's to work properly # fc-match sans.regular DejaVuSans.ttf: "DejaVu Sans" "Book" # fc-match sans:regular:roman DejaVuSans.ttf: "DejaVu Sans" "Book" The jvm command line i used: java -Dprism.useFontConfig=true -Dprism.debugfonts=true -Dprism.verbose=true -cp nalf.jar de.dummy.Main I took a look at the source which produces the line "Not using FontConfig": https://github.com/openjdk/jfx/blob/master/modules/javafx.graphics/src/main/java/com/sun/javafx/font/FontConfigManager.java#L161 If I read correctly the only case where this output can happen is if 'useFontConfig' is false. The only assignment of 'useFontConfig' is here: https://github.com/openjdk/jfx/blob/master/modules/javafx.graphics/src/main/java/com/sun/javafx/font/FontConfigManager.java#L52 useFontConfig should only be false if the property 'prism.useFontConfig' is not equals 'true'. But I set it explicitly to "true" (default should also be true). Does anybody have a clue, what's the problem or has anybody an idea how to debug this further? Best regards Fabian Keller
