原因分析

因为Jira 7.13之后使用了Open JDK 替换了原来的Oracle JDK， 在 AdoptOpenJDJ中并买有包含字体配置包，如果您的操作系统中也缺少字体配置包， 就会导致上述问题


解决方法

安装字体配置包

buntu 


sudo apt install -y fontconfig

CentOS 7


sudo yum install -y dejavu-sans-fonts

CentOS 6

sudo yum install -y fontconfig dejavu-sans-fonts

RHEL 


sudo yum install fontconfig

Debian 


apt-get update && apt-get install -y fontconfig

Fedora


dnf install -y fontconfig



使用Atlassian提供的脚本安装
