Notes

The default font was changed from Utopia to Styx in RHEL 7.4, this is not handled well by the JVM and breaks functionality. For more information see Bug 1484079 – AWT java apps fail to start when stix-fonts is used as sans-serif font

Workaround

1. Stop Jira
2. Create /etc/fonts/local.conf
3. Paste the following:

   <?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>
   

4. Save the file
5. Start Jira

If the above does not fix the issue, install the dejavu-serif-fonts by running the following:

sudo yum install dejavu-serif-fonts
