Betreff: Re: LinkageError: duplicate Class definition
There was a race condition in the web app class loader in 4.0-beta-7 that
could cause this. Could you try it again with a recent nightly build.
NOTE: Use the one from 20010906 (tonight) or 20010904 -- the one from
20010905 has a bug related to session cookies that I just fixed.
