Environment

Release : 6.10

Component : Dollar Universe

Sub-Component: Reporter

Cause

If you are using the docker 'slim images' of openjdk, the image no longer includes the packages 'fontconfig', and 'libfreetype6'.

Check the difference in docker file of openjdk:11-slim and the docker file of openjdk:8-slim.

Resolution

The OpenJDK Hotspot 11 Linux Configuration:

- /usr/java/default symbolic link pointed to the OpenJDK
- /usr/java/latest symbolic link pointed to the jre 8 (in case of rollback)
- launch the update-alternative --install "/usr/bin/java" "java" "<my OpenJDK directory>"
- launch the update-alternatives --config java to change the default java to point to the OpenJDK slot

 

For Tomcat, nothing to do as the alternatives is pointed to the OpenJDK
For UVMS 6.10, nothing to do
For Reporter 6.10, you need to install the fonts and its config (OpenJDK does not contain this)

RHEL/Centos : yum install fontconfig dejavu-sans-fonts dejavu-serif-fonts
Debian : apt install fonts-dejavu fontconfig
SLES/OpenSUSE: zypper install libfreetype6 fontconfig dejavu-fonts

Additional Information

UVMS and Reporter are both pointed to /usr/java/default (the OpenJDK)
