centos下openjdk报:getVersion(FontConfiguration.java)异常,安装fontconfig无效问题的处理
官网jdk包：Releases · dragonwell-project/dragonwell8
背景：
为了适应国产化，使用东方通和国产jdk，从tomcat改为tongweb，从oraclejdk改为国产阿里的龙井jdk
改的
jdk版本：OpenJDK Runtime Environment (Alibaba Dragonwell Extended Edition 8.24.23) (build 1.8.0_442-b01)
OpenJDK 64-Bit Server VM (Alibaba Dragonwell Extended Edition 8.24.23) (build 25.442-b01, mixed mode)
centOS版本：CentOS Linux release 7.5.1804 (Core)
问题：
java项目中使用到验证码，使用oracle版本jdk一切正常，更换openjdk后报如下异常：

问题原因：
缺少字体：dejavu
查看系统已安装字体：
[root@localhost ~]# fc-list
/usr/share/fonts/stix/STIX-Regular.otf: STIX:style=Regular
usr/share/fonts/stix/STIX-Italic.otf: STIX:style=Italic
/usr/share/fonts/stix/STIX-Bold.otf: STIX:style=Bold
发现没有dejavu相关字体。
我的环境使用的是光盘yum源，查找此字体：
[root@localhost fontconfig]# yum provides */dejavu
Loaded plugins: fastestmirror

重新启动项目后问题解决。
