'Upgrading to 11.4.6 causes java.lang.NoClassDefFoundError: Could not initialize class org.docx4j.fonts.IdentityPlusMapper

Case: Writing a docx as pdf using WordprocessingMLPackage and setting the fontMapper using IdentityPlusMapper() from org.docx4j.fonts to map the fonts in the document we receive:

java.lang.NoClassDefFoundError: Could not initialize class org.docx4j.fonts.IdentityPlusMapper

at: getFontMapper()

This happens after upgrading from docx4j 11.2.8 to 11.4.6.

Dependencies in usage are:

org.docx4j:docx4j-core:11.4.6
org.docx4j:docx4j-export-fo:11.4.6
org.docx4j:docx4j-JAXB-ReferenceImpl:11.4.6

Is this a known issue already?

Looking forward to a possible reply!

Thanks in advance.

This seems to be a font loading problem. I'm on a Mac (latest Monterey) and I'm getting the same exception in the contructor call:
