AFAIK, Java forces you to declare method local variables "final" before you can use them in the methods inner class.
This can is be compiled as follows:
for every method local variable copy it at the time of object creation as hidden class variables of the inner class
This works because variables declared "final" cannot be changed once their value is set.
Xuân. :o)
P.S.: This does not necessarily say that trampolines would not work for Java too, maybe they would be faster, but it
would be only possible if the VM can guarantee that the created object will be garbage collectable at the time the
creating method exits, and this case is rather unlikely for most inner classes.
