Hi Cosmin, I use Kepler on Mac OS X 10.4.8, and many of the other developers do as well. I'm not quite sure why you are having an error. Are you running one of the beta releases, or are you running a development snapshot from CVS?
The error you are getting looks to me like a version conflict in one or more of your jar files, possibly your xerces jar file or jena. The system is looking for a method which is not being found, and this is causing an exception while parsing the configuration files. Have you modified the classpath at all? Do you have a new version of any of the jar files in place? Sorry I don't have a more definite solution for you, but I can assure you it works fine on my Mac.
