Reason: the switch to java 11 meant that Forrest did not compile. Apparently the Java 11 compiler will no longer handle the earlier source versions specified in the Forrest build.
I'm still going to update the website, but we're going to also now need to invest in perhaps updating which Forrest version we take. This is not trivial because I had to make customizations to make the PDF generator used the fonts I downloaded for this, and IIRC Forrest later changed in a way which broke my customizations. Karl
