 Trying to compile Lift with 2.8 Beta RC1 and get the following stack
 trace:

 Caused by: java.lang.AssertionError: assertion failed: fatal: $anon has
 owner value $anonfun, but a class owner is required

 To reproduce:

 Get the Lift source:
 git clone git://github.com/dpp/liftweb.git

 cd liftweb
 git checkout -b 280_port origin/280_port
 cd lift-base
 mvn clean install

 Note that during the byte-code emission phase of lift-webkit, the above
 exception appears.
