I'm not sure the prefixing is actually a bug.  site.py probably wants to prefix these things so if the current directory changes, sys.path still works.  It's only weird because '.' is in the path by default which isn't the case in CPython and '__classpath__' is a Jython import hook not a real path.  I'm thinking dropping the . from the default path and special casing __classpath__ in site.py is the right way to go to make this seem a little less weird.
