IS OpenPDF-html available only for Java 21?

[denys-papazov-tw]

IS OpenPDF-html available only for Java version 21 since it depends on OpenPDF 3.0?
Is there a way to port it to previous versions?

[andreasrosdal]

OpenPDF-html requires Java 21. This is a modern and good Java version to use.
You can also try an older version of Flying saucer library,
or create a fork of OpenPDF-html and compile it on an older Java version.
