Description

The following NullPointerException occurs on a Fedora 39 machine:

java.lang.NullPointerException: Cannot invoke "org.apache.fontbox.ttf.CFFTable.getFont()" because the return value of "org.apache.fontbox.ttf.OpenTypeFont.getCFF()" is null
	at org.apache.pdfbox.pdmodel.font.FileSystemFontProvider.addTrueTypeFontImpl(FileSystemFontProvider.java:693)
	at org.apache.pdfbox.pdmodel.font.FileSystemFontProvider.addTrueTypeFont(FileSystemFontProvider.java:635)
	at org.apache.pdfbox.pdmodel.font.FileSystemFontProvider.scanFonts(FileSystemFontProvider.java:379)

	at org.apache.pdfbox.pdmodel.font.FontMapperImpl$DefaultFontProvider.<clinit>(FontMapperImpl.java:139)
	... 90 more

I have also found the offending font: "abattis-cantarell", installed as a dependency of gnome-shell, triggers the bug. After removing the abattis-cantarell font files from my system, the exception did no longer occur.
