PS. jjs of jdk9 is very different (in interactive mode) from that of jdk8u. jdk9 versions on jline+many other desktop stuff and so would load lot more code.
Right, I noticed that on jdk8 running the exit.js script loads fewer classes (1827), while on jdk9 we load 2359 classes right now (down from 2450 OOTB thanks to the --generate-jli-classes plugin and other work on improving indy bootstrap[1]). When I link a custom image with a --generate-jli-classes configuration created by running jjs exit.js I can currently get it down to 2114 classes loaded (meaning we're avoiding generating more than 300 LF classes at bootstrap), which together with the small heap tuning puts startup of jjs on 9 well on par with 8.
