Environment

Release : 12.x and 21.x

Component : AUTOMATION ENGINE

Sub-Component: Any graphical tool that requires X11, such as dbload

Cause

By default, Openjdk does not include the necessary fonts and font configurations in Linux/Unix distributions.

Resolution

The problem is related to the lack of fonts and font configuration within the Openjdk versions of Java.
in order to fix it, please install the necessary packages in the Server hosting the Automation Engine according to your distribution as mentioned here

For Linux:

Debian/Ubuntu/Mint: apt-get install libfreetype6 fontconfig fonts-dejavu
RHEL/CentOS/Fedora: yum install freetype fontconfig dejavu-sans-fonts
SLES/OpenSUSE: zypper install libfreetype6 fontconfig dejavu-fonts
