JavaFX использует моноширинный шрифт для всех элементов управления

Я использую JavaFX 1.8u40 на рабочей станции Red Hat Enterprise Linux Workstation версии 6.6 (Сантьяго). Когда я запускаю стандартное приложение JavaFX даже без дополнительного CSS, все метки, меню и т. д. отображаются с использованием моноширинного шрифта.

В системе, которую я использую, доступны только следующие шрифты TTF.

/usr/share/fonts/liberation
/usr/share/fonts/liberation/LiberationSerif-Regular.ttf
/usr/share/fonts/liberation/LiberationMono-BoldItalic.ttf
/usr/share/fonts/liberation/fonts.dir
/usr/share/fonts/liberation/LiberationMono-Italic.ttf
/usr/share/fonts/liberation/LiberationSans-Bold.ttf
/usr/share/fonts/liberation/LiberationSerif-Bold.ttf
/usr/share/fonts/liberation/LiberationMono-Regular.ttf
/usr/share/fonts/liberation/LiberationSans-BoldItalic.ttf
/usr/share/fonts/liberation/LiberationSerif-Italic.ttf
/usr/share/fonts/liberation/LiberationSerif-BoldItalic.ttf
/usr/share/fonts/liberation/fonts.scale
/usr/share/fonts/liberation/LiberationSans-Regular.ttf
/usr/share/fonts/liberation/LiberationSans-Italic.ttf
/usr/share/fonts/liberation/LiberationMono-Bold.ttf

Я отладил это с помощью -Dprism.debugfonts из руководства по шрифтам OpenJFX. Вывод следующий.

FC name=sans style=0 uses Liberation Mono in file: /usr/share/fonts/liberation/LiberationMono-Regular.ttf

Я обнаружил, что использование -Dprism.useFontConfig=false приводит к тому, что JavaFX по умолчанию использует встроенные шрифты Lucida, однако мне нужно использовать файлы Liberation в /usr/share/fonts

Вопросы

  • Как мне интерпретировать вывод prism.debugfonts? Что означают строки 0, 1, 2? Я не могу найти документацию для этого в Интернете.
  • Почему JavaFX выполняет логический шрифт без шрифта с моноширинным шрифтом?
  • Как я могу заставить JavaFX использовать Liberation Sans вместо моно? В идеале без необходимости изменять установку JDK...
  • Это проблема JavaFX или проблема с fontconfig?

Проблема заключается в правилах fontconfig в /etc/fonts/conf.d/, а не в JavaFX. Я еще не смог понять, как это исправить, но использование fc-match дает те же результаты.

fc-match sans:regular:roman 
"LiberationMono-Regular.ttf": "Liberation Mono" "Regular"

Я обнаружил аналогичную проблему на другом форуме: Проблема со шрифтом, моноширинный шрифт используется для шрифтов с засечками и без засечек. семей, но без решения.

Добавление файла конфигурации шрифта, например. /etc/fonts/conf.d/88-liberation-hack.conf решит проблему
