logback status looks ok. But could not see the status on browser

when i access https://localhost:8443/lbClassicStatus , it's works fine but not https://localhost:8443/lbAccessStatus

I spent a whole day looking at BasicStatusManager class and all the other stuff , but no luck.

is there anything i am missing or is it really a bug?

Thanks.
