Was there an error message display on the console? Or in the log file? The error text posted so far doesn't give me much to work with. I have run 2.4.0 with MySQL and PostgresSQL in XP and FC5 without seeing this error. I have seen some "error" messages show up on the console, I think they were JSF-related; I just ignored them and the Management Portlet displayed just fine.
