I moved the issue to the repo with the CKEditor 4 builder.

Could you check if the builder works with older version of Java (8 or 11)? Probably it would be the easiest workaround for now.

Thanks @Comandeer, I ran this in Java 11 OpenJDK and got the following warning:

Generating plugins sprite image
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.mozilla.javascript.MemberBox (file:/opt/....../ckbuilder.jar) to method sun.java2d.SunGraphics2D.drawImage(java.awt.Image,int,int,java.awt.image.ImageObserver)
WARNING: Please consider reporting this to the maintainers of org.mozilla.javascript.MemberBox
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

No stack trace, exit code 0 :)

Like #27, this error with Java 17 need to be fixed by rihno: mozilla/rhino#462 hopefully in their next version v1.7.14 as adding --add-exports java.desktop/sun.java2d=ALL-UNNAMED to jvm arguments seem not work in java 17 for me.

[SuperPat45]

I successfully recompiled CKeditor4 with Open JDK 17!

You need to recompile CKBuilder.jar by upgrading mozilla rhino with the latest version v1.7.14
You need to add the JVM argument --add-exports java.desktop/sun.java2d=ALL-UNNAMED to your command line

We came across one issue of Riho which is used in elixir repertoire server. We got below error and laber/reports not getting printed properly.
ERROR, JavaScript - JavaScript eval: Error evaluating script: java.lang.IllegalAccessException: class org.mozilla.javascript.MemberBox cannot access class sun.java2d.SunGraphics2D (in module java.desktop) because module java.desktop does not export sun.java2d to unnamed module @483f6d77

We resolved above issue by passing below argument while starting Repetior Server using java 17.
java --add-opens java.desktop/sun.java2d=ALL-UNNAMED
