Captcha appears warped and unreadable and chart gadgets that print graphics show garbled text and weird symbols when running JIRA in Linux

Issue Summary

• Captcha appears warped and unreadable and chart gadgets that print graphics show garbled text and weird symbols when running JIRA in Linux

Steps to Reproduce

• Attempt to login with captcha activated or add a gadget like the Pie chart gadget.

Expected Behavior

• Captcha is readable
• Gadgets printing graphics and text have characters humanly readable.

Actual Behavior

• Captcha appears warped and completely unreadable:
  
• Gadgets with graphics print garbled characters:
  

Cause

• Apparently, system fonts.

Workarounds

• Workaround 1
  • Install the following packages (usually the fonts are enough but it is recommended to also include Ghostscript and Motif):

    yum install ghostscript
    yum install dejavu-fonts-common
    yum install dejavu-sans-fonts
    yum install dejavu-sans-mono-fonts
    yum install motif

• Workaround 2
  • It has been reported that, when already having the previously mentioned font packages, other font packages seem to interfere, specifically it has been mentioned that having installed lyx-fonts (Lyx/MathML fonts - A collection of Math symbol fonts for lyx) caused this issue, and removing the package solved it.

Notes

• This bug ticket has been raised due to JIRA requiring something to work that is not included in the installation package nor in the documentation as a requirement.

Environment

• Linux RedHat
