[Jersey] Re: PermGen Memory Leak in Tomcat

IMHO it's not an issue of Jersey but Tomcat. We had many problems like
that (after few redeployments we need to restart Tomcat because of
PermGenSpace) in production though we don't use Jersey in these
production applications. We "solved" it with sheduled restarts in
regular service breaks. :(
Please try to search Tomcat forum for suggestion.
