Róbert Csákány updated SLING-2806:
----------------------------------
Attachment: SLING-2806-fix.diff
The problem is the loading of javax.script.ScriptEngineFactory file. By default
the config loader handles the # comments, but the empty lines isn't, so trying
to load invalid class (empty name).
The fix is attached.
