I have created a snapshot of JRubyArt-1.7.0 as a wrapper to support anyone wishing to stick with the original JRubyArt. This I have named JRubyArtLegacy and unless anyone wants to take it forward I am proposing a final release to match JRuby-9.2.8.0 release (and stuck with using jdk-1.8.0). Thereafter developing JRubyArt-2.0 as a stand-alone ruby implementation of processing (not tied to vanilla processing) and supporting the use jdk11+.
