This isn’t a generalisable answer, but in this particular case, you can download and install the Debian 10 version of the package:

wget http://deb.debian.org/debian/pool/main/j/jetty9/libjetty9-java_9.4.15-1_all.deb
sudo dpkg -i libjetty9-java_9.4.15-1_all.deb

Its dependencies will already be satisfied on your system.
