JIRA Charting Plugin, Workload pie chart font problem

Sarah Baker

Just updated from JIRA 7.4 to 7.13 on CentOS system.

The Workload Pie Chart now breaks for everyone with the below.
It's looking for a font config file?  

Any clues appreciated.

I found a very similar error in a related thread of https://community.atlassian.com/t5/Jira-Software-questions/Error-500-when-generating-charts-after-upgrading-from-7-6-3-to-7/qaq-p/739967

In that case, the user found that his system was using a different JDK.   Jira 7.13 is the first version to provide support for openjdk in addition to the previously supported Oracle JDK/JRE versions of Java.   More details in the Supported platforms doc.  

I'd recommend using either of the supported versions of Java for that version to avoid this specific error.
