From http://www.javac.info/issues-v05.html :

"The system class loader should dynamically generate function type interfaces.
The interfaces corresponding to function types should be generated on demand by the bootstrap class loader, so they can be shared among all user code. For the prototype, we may have javac generate these interfaces so prototype-generated code can run on stock (JDK5-6) VMs."
