some nashorn testing

[Marcus Lagergren]

My bad. This actually reproduces through the JSR223 bridge. Must be an eval related problem. I am on it!

I still get nothing when I manually build the latest nashorn.jar from the openjdk and run the JS snippet from the command line with java -jar nashorn.jar <program.js>  (Haven't gone through the script engine bridge, but as it seems to be a JavaScript problem it should be sufficient to run it as a standalone script). This very much looks like a bug that I fixed before christmas and pushed into the closed repo - I've verified that it made it into the openjdk source.
