PuffinPlot downloads Jython at runtime on first use of the Python scripting feature. This feature is currently broken, since the central.maven.org endpoint which it was using has been retired. The hardcoded Jython URL in PuffinPlot should be updated to point to one of the current canonical HTTPS endpoints, https://repo1.maven.org or https://repo.maven.apache.org, as described at https://central.sonatype.org/faq/ssl/.
