compile 'org.apache.poi:poi-ooxml:3.14'

Environment :

• openjdk version "1.8.0_141"
• RedHat 7.4
• wildfly 10.0.0

Answer 1

The issue happened only on Red hat version 7.4. it is reported there. and the Red hat guys are working to fix it here. the solution I found is just to provide the fonts in order to force back Utopia as the default font, used by java.

Create the following file /etc/fonts/local.conf with the following content:

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
  <alias>
    <family>serif</family>
    <prefer><family>Utopia</family></prefer>
  </alias>
  <alias>
    <family>sans-serif</family>
    <prefer><family>Utopia</family></prefer>
  </alias>
  <alias>
    <family>monospace</family>
    <prefer><family>Utopia</family></prefer>
  </alias>
  <alias>
    <family>dialog</family>
    <prefer><family>Utopia</family></prefer>
  </alias>
  <alias>
    <family>dialoginput</family>
    <prefer><family>Utopia</family></prefer>
  </alias>
</fontconfig>

Make sure the file is readable by the correct user.
