    Description

      https://pdfbox.apache.org/3.0/getting-started.html

      This page contains possibly obsolete advice: "Due to the change of the java color management module towards "LittleCMS", users can experience slow performance in color operations"

      The bug that's linked to as explanation was marked as fixed in Java 18. It turned out that LittleCMS wasn't ever the problem really, but rather inefficient use of JNI:

      https://github.com/openjdk/jdk/pull/5835

      So hopefully this advice can now be gated on "If you are using lower than Java 18"
