Description

I'm seeing these warnings:

2022-01-16 16:49:05,723 WARN  [org.apa.pdf.pdm.fon.FileSystemFontProvider] (executor-thread-10) Building on-disk font cache, this may take a while
2022-01-16 16:49:05,724 WARN  [org.apa.pdf.pdm.fon.FileSystemFontProvider] (executor-thread-10) Finished building on-disk font cache, found 0 fonts

which are pretty much useless because creating a basically empty cache will not take a while.

These warnings should only be logged if there actually are font files.

PS: My case is a Quarkus app running as a docker container based on azul/zulu-openjdk-alpine:17.0.1-jre-headless.
