Yes, but this doesn't solve the problem concerning JDK. If you 
disassemble the code generated
from the classes provided by Ito you may notice that the inner class 
doesn't have any protection
although it is protected. But I've made another test with private and 
apparently it changes something also
concerning the modifier, so the problem should be more complicated.
