JSR223 Script Engine with JavaScript

I have a problem getting the JSR223 Script Engine to work on OpenHAB 1.7. I did install the add-on and put a test.js to the scripts folder (content from the wiki page).
Even with the log level set to TRACE on org.openhab I get no lo output whatsoever.
Is there anyone having this work?

tnx and cheers,

I figured it out myself. The JSR223 OSGI bundle is broken for the 1.7.1 build on the download page. I checked out the sources and the HEAD works fine.
