This was for JShell. It also seemed that this needed a java executable in the bin directory. I added that manually and was able to use JShell from a OS X java 9 application.

I realize this is going off-topic but can you elaborate more on this. There should never be a need to copy binaries into the bin directory. The jdk.jshell module includes jshell launcher for example.

I got a JShell JRE with —add-modules I initialize a JShell shell with… private static final JShell shell = JShell.create(); Without java in the bin directory the first time I try to use the shell with…

        List<SnippetEvent> result = shell.eval(sb.toString());
        for (SnippetEvent evt : result) {
            System.out.println(evt.value());
        }

I get…
