some nashorn testing

[Marcus Lagergren]

Where did you get/build your nashorn.jar? We'll get proper versioning in there as soon as we've integrated fully with the OpenJDK build system. 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.
