Cfimage captcha error :: java.lang.reflect.InvocationTargetException

Hi.

New to Lucee and ran into an odd issue. I am using CFIMAGE with the captcha action.
There is no problem in my computer but an error is occured in the server.
My source code and the error message is below;

ㅇ System information
[ My computer ] [ Server ]
- OS : Windows 10 (64bit) - CentOS 7 (64bit)
- Lucee version : 5.3.2.77 - 5.3.2.077

What is the problem and how can i fix it?

Help me.

looks like this bug

https://bugs.openjdk.java.net/browse/JDK-8204688
https://bugs.launchpad.net/ubuntu/+source/openjdk-lts/+bug/1780151

which version of java are you running?

My computer is 1.8.0_191 and server is 1.8.0_212.

as per that ubuntu link, I think you need to install a font library as your linux server is probably headless

see the comments on https://luceeserver.atlassian.net/browse/LDEV-1943

I requested to server manager to install font package but I was refused.
So, it is imposible to fix it in my case.

Anyway, thank you.
