2.1.0 doesn't bring in Graal?

[ibrahimatcha]

When I try to run config.setExpressionHandler(new GraalJsExpressionHandler()); using 2.1.0 I get the following exception java.lang.ClassNotFoundException: jdk.vm.ci.services.Services. I also get this issue in 2.0.6, 2.05 and 2.04.

When I go down to 2.0.3, this issue disappears, although I still have other problems (brought up in https://github.com/neuland/pug4j/issues/25) but that's separate.
