[fniephaus]

Have you created appropriate reachability metadata for your project (e.g., using the trace agent)?

[kristofdho]

@fniephaus sun.awt.FontConfiguration#findFontConfigFile does require the java.home property, together with the fontconfig.bfc file located somewhere in that java home directory. All required for the fontmanager library.
We currently use a workaround to include this bfc file as a resource, and some substitutions in sun.awt.FontConfiguration to use this internal resource instead of looking for one in the java.home dir.
It's a solution that works for us, but not generic enough to put in a PR as it hardcodes the used config file and removes the ability to specify your own config through the sun.awt.fontconfig property.

TLDR, issue comes from using the FontManager library stuff, and can't be solved by using the tracing agent (although there is indeed some JNI configuration required).

@iceman567 please check the workaround provided by @kristofdho or this one #3393 (comment) and let us know if that fixes the issue.

@iceman567 please check the workaround provided by @kristofdho or this one #3393 (comment) and let us know if that fixes the issue.

step 1: 【important】
System.setProperty("java.home", "./");

step 2:
copying ${java.home}\lib to .\lib in app folder.

${java.home}\lib\fontconfig.bfc
${java.home}\lib\fontconfig.properties.src
${java.home}\lib\psfont.properties.ja
${java.home}\lib\psfontj2d.properties

step 3:
