As I reported in my previous post:
https://groups.google.com/group/google-appengine-java/browse_thread/thread/3486790b7f5fd061,
I am having this PermGen issue consistently now.
I think that it's really related to local dev environment support for
Backend service. Please take a look at following stacktrace. It
originated from BackendServersFilter. If I disabled Backend Service on
my local dev, I don't have PermGen issue.
