java.lang.NullPointerException at sun.awt.FontConfiguration.getVersion(FontConfiguration.java:1264)

Hello All,
We have a Java (with JBOSS as app server) based application with GUI. While generating jasper letters from the application, we are getting exceptions in log. we dont use docker.

Env Details:-
openjdk version "1.8.0_282"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_282-b08)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.282-b08, mixed mode)

cat /etc/redhat-release

Red Hat Enterprise Linux Server release 7.6 (Maipo)

There is a file fontconfig.properties available at $JAVA_HOME/lib, with below two lines in it.
version=1
sequence.allfonts=default

exception

javax.ejb.EJBException: net.sf.jasperreports.engine.JRRuntimeException: Error initializing graphic environment.
...
Caused by: net.sf.jasperreports.engine.JRRuntimeException: Error initializing graphic environment.

Caused by: java.lang.NullPointerException

ERROR [net.sf.jasperreports.engine.util.JRStyledTextParser] (default task-19) Error while loading available fonts: java.lang.NullPointerException
at sun.awt.FontConfiguration.getVersion(FontConfiguration.java:1264) [rt.jar:1.8.0_282]

Reading other threads on github, i found a suggestion to install the fontconfig (sudo yum install fontconfig dejavu-sans-fonts dejavu-serif-fonts ), however this hasn't worked for all.
Could you please suggest what can i do as workaround to get passed this issue.

Regards,
Alok

Maybe it is worth looking a this post on Stack Overflow: https://stackoverflow.com/questions/45569367/upgrade-rhel-from-7-3-to-7-4-arrayindexoutofboundsexception-in-sun-font-composi/45600582#45600582

Hello @titou10titou10 ,
Thanks for your input.
In my case , as mentioned the RHEL version is 7.6 and the error i am getting while generating Jasper PDF letter is not ArrayIndexOutOfBound, but rather its as below.

Do you think creation of a file /etc/fonts/local.conf (with the content suggested in the link you gave) could be a possible resolution?

@alokbaranwal honestly I don't know. You problem seems similar in some way to the one we hit months ago, ie jasper + java8 + rhel v7.x + awt ... complaining with font problem... Probably you could give it a try.
I though the link I gave could give you a clue. If not then sorry for the noise
