But I am using Lift 2.0 snapshot, I got the following exception:
INFO: Illegal access: this web application instance has been stopped
already. C
ould not load
net.liftweb.http.SessionMaster$$anonfun$1$$anonfun$apply$11$$anonf
un$apply$12. The eventual following stack trace is caused by an error
thrown fo
r debugging purposes as well as to attempt to terminate the thread which
caused
the illegal access, and has no functional impact.
